MathProblem-Solving and Data AnalysisHard
A store raises the price of a jacket by 20%. Later, it lowers the new price by 20%. The final price is what percent of the original price?
A80%
B96%Correct
C100%The trap
D104%
Check with $100: $100→then$120→then$96
Turn each change into a multiplier.
Up 20% means × 1.20. Down 20% means × 0.80.
Apply them in order.
1.20 × 0.80 = 0.96
Read the answer.
The final price is 96% of the original. That’s B.
Why not 100%?
The 20% cut is taken from the higher price, so it removes more than the 20% increase added.

98 questions across four modules, in the same order as the digital SAT: Reading & Writing Module 1 and Module 2 (27 questions each), a 10-minute break, then Math Module 1 and Module 2 (22 questions each). On official timing that’s 2 hr 14 min of testing. You get estimated section scores and a total at the end.
Yes. In the standard full-length tests, Module 2 of each section is the harder version if you get 60% or more of Module 1 right, and the easier version if you don’t. Challenge tests are built from harder material in every module.
Official timing, extended 1.5× time, or untimed, on every test, including the free ones. Extended time allows 48 minutes for each Reading & Writing module and about 52 for each Math module. Untimed removes the clock so you can focus on accuracy.
A quick run with three hearts. Each right answer builds your streak: the questions get harder as it grows, and your points multiply (×2 from three in a row, ×3 from six). A miss costs a heart and drops you back to easy. Best is your longest streak.

Organization, Transitions and Cohesion · Lesson 1
Transitions between sentences and paragraphs
A transition is a word or phrase such as however, as a result, or for example that tells the reader how a sentence relates to the one before it. Every transition makes a claim about logic. However says "the next idea pushes against the last one." As a result says "the next idea was caused by the last one." If the claim is false, the transition is wrong, even when the sentence still sounds smooth.
Use the same routine every time. First, cover the underlined transition. Second, read the sentence before it and the sentence it starts. Third, name the relationship in your own words: contrast, cause and effect, addition, example, time order, or restatement. Only then look at the choices and pick the one that matches.
| Relationship | The next sentence... | Transitions |
|---|---|---|
| Contrast | pushes against or limits the last idea | however, nevertheless, even so, still, instead, in contrast, on the other hand |
| Cause and effect | is a result of the last idea | therefore, as a result, consequently, thus, so |
| Addition | adds a similar point | in addition, moreover, furthermore, also, similarly |
| Example | gives a specific case of the last idea | for example, for instance |
| Time order | happens before, during, or after | first, then, afterward, meanwhile, finally |
| Restatement | says the same idea in other words | in other words, that is |
Worked example Easy
Honeybees cannot see the color red the way people do; to a bee, a red flower looks dark and dull. Therefore, bees can see ultraviolet light, which reveals patterns on many flower petals that human eyes cannot detect.
Which choice is most logical?
- NO CHANGE
- However,Answer
- For example,
- In other words,
How to solve it
- Cover the transition and read both sentences. Sentence 1: bees cannot see red the way people do. Sentence 2: bees can see ultraviolet light that people cannot.
- Name the relationship: a weakness, then a strength. That is a contrast.
- Only However signals contrast. Therefore claims a cause, For example claims an example, and In other words claims a restatement.
Why each choice is right or wrong
- A. Incorrect. Therefore says that seeing ultraviolet light is caused by being unable to see red, and the passage gives no such cause.
- B. Correct. The first sentence names something bees cannot see, and the second names something they can see that people cannot. That is a contrast: However, bees can see ultraviolet light.
- C. Incorrect. For example would make ultraviolet vision a case of not seeing red, but it is the opposite kind of fact: an ability, not a limit.
- D. Incorrect. In other words signals a restatement, yet the second sentence adds a new fact about ultraviolet light instead of repeating the first.
Worked example Medium
The community garden on Elm Street began with just six raised beds. Within three years, more than forty families had signed up for plots, and the waiting list kept growing. Nevertheless, the town council voted to double the size of the garden the following spring.
Which choice is most logical?
- NO CHANGE
- For instance,
- Even so,
- As a result,Answer
How to solve it
- Name the relationship. Many families want plots and the waiting list keeps growing; then the council doubles the garden. The demand is the reason for the vote.
- That is cause and effect, so look for a result transition.
- Notice that Nevertheless and Even so signal exactly the same relationship (a contrast with what came before) and work the same way in this sentence, so they stand or fall together; neither fits a cause-and-effect link. For instance signals an example, which leaves As a result.
Why each choice is right or wrong
- A. Incorrect. Nevertheless signals that the council acted in spite of the demand, but a long waiting list is a reason to expand the garden, not an obstacle.
- B. Incorrect. For instance would make the council's vote an example of families signing up, but the vote is a response to that demand.
- C. Incorrect. Even so means the same thing as Nevertheless: it treats the growing waiting list as a reason not to expand, which reverses the logic.
- D. Correct. The growing demand caused the council to expand the garden, so the cause-and-effect transition fits: As a result, the town council voted to double the size of the garden.
Trap Judging the transition by sound
Most wrong transitions sound fine in the sentence. Nevertheless, the council voted to double the garden is smooth English; it is only wrong because it misstates the logic. Always decide the relationship before you read the choices, so a smooth-sounding choice can't talk you into it.
As a backup after you have named the relationship: if two choices signal exactly the same relationship and work the same way in the sentence (nevertheless and even so, for example), they can't both be the single right answer. Near-synonyms are not always interchangeable, though (but and however need different punctuation), so check before you cross a pair out.
Trap Forgetting that DELETE is a real option
Sometimes the sentence already contains a connecting word, such as but or so, and the underlined transition repeats it: It rained, but however, the game went on. In that case the best answer is to delete the extra transition. Fill the deletion into the sentence and check that what is left is complete and clear before you choose it.

Privacy Policy
Last updated October 10, 2026
Peakscor is an independent SAT®, ACT® and AP® practice website at peakscor.com, built and run by its student founders in Houston, Texas. This policy explains what we collect, why, and what you can do about it. If anything here is unclear, email support@peakscor.com.
The short version
- You can practice without an account. Your progress saves to an anonymous guest account with no name or email, and some of it stays only in your browser.
- If you make an account, we also keep your email address, so your progress can sync across devices.
- We don’t sell your data, show ads, or use third-party analytics or advertising trackers.
- Peakscor is for students 13 and older.
- Kip, our AI tutor, sends the messages you write to it to Anthropic, the company that makes the AI, so it can answer. Your chats with Kip stay on your device. Our servers keep only how many messages you sent, never what you wrote.
- Points you earn put you in a weekly league where other students see your display name, points and rank. You can hide yourself from leaderboards at any time.
- You can delete your account and its data at any time from the account menu.
What we collect
In your browser only
Some things are saved only in your browser’s local storage and are never sent to us: the calculator’s layout and saved entries, your practice difficulty and timing, the test you chose last (SAT, ACT or AP), your light or dark theme, your best scores on the Daily, today’s practice numbers, a test in progress, the questions you’ve seen recently, and the copies of missed questions in your mistake notebook. Your game and study settings, your practice and full-test results, your study plan and your diagnostic result are kept in your browser too, and a copy is saved to your guest account or account so they can follow you to another device (see below). You can remove the browser copies by clearing your browser’s site data for peakscor.com.
Your daily free-question count is kept in your browser and on our servers, counted per account and per browser, so the free limit works the same in a private window. The browser is identified only by a scrambled (hashed) version of its random ID, and each count is just a number of questions per difficulty for that day.
Guest progress, without an account
So your progress can save, Peakscor creates an anonymous guest account in the background when you visit. It has no name or email address. It is tied to a random ID created when you first visit. It stores:
- your game coins, characters and map progress;
- your game and study settings (for example sound, question difficulty in the games, how explanations are shown, and display and control preferences);
- your practice record: which questions you have seen or missed, your answers to practice questions (which choice, whether it was right, and how long it took), and your accuracy by skill and topic;
- your full-test scores, your study plan (test date, target score, study days) and your diagnostic result;
- which test (SAT, ACT or AP) each piece of your study data belongs to, if you use more than one;
- which parts of Peakscor you used each day (for example, practice, games, the diagnostic or a video), so streaks and your study plan work and so we can count how often each feature is used.
Points and weekly leagues
When you answer a Practice question correctly, finish a lesson, master a module, finish the diagnostic or finish a game, you earn points. We store each award with what earned it (for example a question or lesson ID), the points, the day and the time, plus how long you took to answer, and the league tier you are in. Each week you are placed in a league of up to 30 students at your level. Other students in your league see your display name, your points that week and your rank. They never see your email or anything else about you. Turn on “Hide me from leaderboards” on the Leagues page to stop showing up on any leaderboard right away; you still earn points and see your own total. Points from every test (SAT, ACT and AP) count toward the same weekly league; only you see how your points split by test. Points and league results are kept until you delete your account.
Badges and Kip’s outfits
As you study, you earn badges (for example for a 7-day streak, finishing the diagnostic or mastering a unit) and outfits for Kip, the Peakscor mascot. We work them out on our server from what you have already done on Peakscor, and store which badges you earned, when, and which outfit Kip is wearing. Badges and outfits can only be earned, never bought. Other students don’t see your badges. They are kept until you delete your account.
Duels
If you start or join a duel, we store that you are one of its two players (your account ID, never a name or email), the five questions, each answer you give (which choice, whether it was right and how long it took), your score and any points it earned you. The other player sees your display name, how many questions you have answered, whether you got each one right once they have answered it too, and your final score. They never see which choice you picked, your email or anything else about you. If you hide yourself from leaderboards, they see “A climber” instead of your name. Anyone you send the link to sees your display name on the invite. Each duel belongs to one test (SAT, ACT or AP), and both players see which. A duel and its answers are deleted 30 days after it ends.
Reminders (push notifications)
Reminders (push notifications), only if you turn them on. When you tap “Turn on reminders” and allow notifications, your browser gives us a push address and two encryption keys for this device. We store them with your account id, your time zone (so we never send before 8 AM or after 9 PM where you are) and the date of the last reminder. We send at most one reminder a day: a duel waiting for your turn, your Summit Sprint day, a streak about to slip, or league news. They never include your name, score or email. Turn them off any time on Home, in Progress or in your account (one tap removes every device); deleting your account deletes them too. Unused for 120 days, they are deleted.
Classes
If you join a teacher’s class, we store that you are in the class and the nickname you choose for it. Please don’t use your real name. The teacher sees your nickname and a short summary of your studying: active days in the last week, Learn lessons completed and modules mastered, your diagnostic levels, your practice accuracy by topic, and whether you have finished their assignments. The teacher never sees your email address or your answers, and other students never see your data. If you leave the class, or the teacher removes you, the teacher no longer sees any of it. A teacher’s account stores the class name and its join code.
With an account
- Your email address, used to sign you in and to send sign-in links and password-reset codes. Passwords are handled by our sign-in provider and stored only in hashed form. We never see your password.
- A display name. New accounts get an anonymous name like “Climber 4F2A1”. It is never taken from your email.
- Your progress: everything a guest account stores, plus your Learn lesson and quiz progress, synced across your devices.
- The Summit Sprint, if you join it: the day you joined, your goal, and for each day you finished the daily climb, how many questions you answered, how many were right, how long it took and the points it earned. We don’t keep which questions they were or your answers to them in the sprint. The sprint leaderboard shows your display name, days climbed and sprint points to other students, unless you hide yourself from leaderboards.
- Classes you teach, if any: the class name, its join code and its assignments.
- Billing records, if you ever buy a plan: your Stripe customer ID and subscription status. Card details go straight to Stripe. We never receive or store them.
Technical information
Like any website, our hosting providers process your IP address and basic request details (such as browser type) to deliver pages and keep the service secure. A sign-in token for your guest account or account is kept in your browser’s local storage. When someone makes an account, we keep the email address they signed up with and scrambled (hashed) versions of their IP address and browser ID for up to 31 days, only to stop disposable email addresses and limit how many accounts one network or browser can create. If a page breaks, your browser may send us a short error report: what went wrong, which page it happened on (without anything after the “?” in the address), the site version and your browser type. Email addresses and sign-in tokens are removed from it, and it doesn’t include your user ID or email address. We keep error reports for about 30 days. We don’t use advertising cookies or third-party analytics tools.
Kip, the AI tutor
Kip is Peakscor’s study helper. Kip is an AI (a computer program), not a person, and it can make mistakes, so check anything important against the lesson or the question’s explanation. Kip is turned off during full tests, the diagnostic and mastery quizzes.
What happens when you message Kip
- Your chats stay on your device. Your messages and Kip’s replies are saved only in your browser’s local storage. Peakscor’s servers don’t keep what you write or what Kip answers: it isn’t saved in our database or in our logs. Because we don’t keep chats, we can’t show them to anyone, including a parent or a teacher, and we can’t get them back if they’re deleted.
- Each message is sent to Anthropic to get an answer. Anthropic makes Claude, the AI model behind Kip. With each message, our server sends Anthropic what you typed, the recent messages in that chat, what you’re looking at (for example the question on your screen and, once you’ve answered it, your answer and the explanation), and a short summary of your own study progress: for example your weakest skills, questions you recently missed, Learn modules you’ve finished, your diagnostic levels, and your study plan’s test date and target score. We don’t send your name, email address, display name or account ID.
- Please don’t share personal details like your full name, address, phone number or school with Kip. Kip doesn’t need them, and anything you type is sent to Anthropic.
How Anthropic handles your messages
Anthropic handles messages for us as a service provider, under its commercial terms. Those terms say Anthropic doesn’t use them to train its AI models. Anthropic deletes them within 30 days, except that it can keep a message for up to 2 years if its safety systems flag it as breaking Anthropic’s usage policy, or for longer if the law requires.
What we keep
For each account and guest account, we count how many messages were sent each day and estimate what they cost, so the daily limits work. We keep these counts for 90 days. For the whole site, without recording who, we also count how many times each kind of safety topic came up each day (for example, someone asking Kip to help cheat, or someone who seemed to be in crisis). None of these counts include anything anyone wrote.
Daily limits
Kip answers a limited number of messages a day: right now 10 on the free plan (and for guests), 30 on Pro and 60 on Peak. Limits reset at midnight Central Time. We may change them, and Kip may take a break for everyone for the rest of the day if Kip’s daily budget runs out.
Deleting your chats
Open Kip’s menu and choose Delete history to erase every chat with Kip on that device. Signing out or deleting your account also clears them. Messages already sent to Anthropic are deleted on Anthropic’s schedule above.
If you’re going through something hard
Kip is a study helper, not a counselor. Nobody at Peakscor reads your chats, so Kip can’t send anyone to help you. If you’re thinking about hurting yourself or you don’t feel safe, call or text 988 (the Suicide & Crisis Lifeline) any time, day or night, and tell a trusted adult, like a parent, school counselor or teacher, right away. If you’re in immediate danger, call 911.
How we use it
Only to run Peakscor: to sign you in, save and sync your progress, grade questions, answer your questions to Kip, show leaderboards, keep the service secure and fair, handle payments if you buy a plan, and reply when you contact us. We don’t use your data for advertising, and we don’t use it to train AI models.
Who we share it with
We don’t sell or rent personal information. We use a small number of service providers who process data only to run Peakscor:
- Supabase stores account data and handles sign-in, including sign-in emails. Its servers are in the United States.
- Vercel hosts the website.
- Stripe processes payments, only if you buy a plan.
- Google Fonts supplies the lettering in two of the games (Peak Hoover and Peak Defense). When those games load, Google receives standard technical information such as your IP address.
- Your browser’s push service (Apple for Safari and iPhone/iPad Home Screen apps, Google for Chrome and most Android browsers, Mozilla for Firefox, Microsoft for Edge on Windows): delivers the reminders you turned on. It receives the encrypted reminder (it can’t read it) and the push address your browser created; Peakscor doesn’t choose it, your browser does. Only if you turn reminders on.
- Anthropic provides the AI model behind Kip. Only when you use Kip, it receives the messages you send and the information listed under “Kip, the AI tutor”. It doesn’t receive your IP address, name or email address.
We may also share information if the law requires it, or to protect the safety of students or the security of the service.
What other people can see
Game leaderboards are public and show your display name and your scores. They never show your email address. If you join a class, its teacher sees the summary described under “Classes”. In a duel, the other player sees what is described under “Duels”. Other students in your weekly league see your display name, points that week and rank, and the Summit Sprint board shows your display name, days climbed and sprint points, unless you turn on “Hide me from leaderboards”. Nothing else about your account is public.
Students under 13
Peakscor is meant for students 13 and older, and we don’t knowingly collect personal information from children under 13. If you believe a child under 13 has made an account, email us and we will delete it.
Your choices
- Delete your account: open the account menu and choose Delete account. This permanently erases your account and everything stored with it on our servers, and clears Peakscor’s data in that browser.
- Guest data: if you never made an account and want your guest data deleted, email us and we’ll help.
- Delete your chats with Kip: open Kip’s menu and choose Delete history.
- Clear data on your device: clear your browser’s site data for peakscor.com.
- See, correct or get a copy of your data: email us from the address on your account and we’ll respond within 30 days.
These choices are available to everyone, wherever you live.
How long we keep it
We keep account and guest data until it is deleted. Duels are deleted 30 days after they end. Kip message counts are kept for 90 days, and your chats with Kip stay on your device until you delete them. When you delete your account, it is erased from our database right away. Copies in our providers’ encrypted backups are overwritten on their normal schedule, usually within a few weeks.
Security
All traffic is encrypted. Every database table has access rules so that each student can read only their own records, and those rules are tested automatically whenever the code changes. No system is perfectly secure, so if you think something is wrong, tell us right away.
Schools
Peakscor is independent. It isn’t provided by or through any school, and we don’t receive student records from schools. A teacher can make a Peakscor class and invite students with a code; joining is up to each student, and the teacher sees only the class summary described under “Classes”.
Changes
If we change this policy, we will update the date at the top. If a change affects how we use data you’ve already given us, we will tell you on the site before it takes effect.

How our questions are made
Last updated October 10, 2026
Every question, passage, explanation and lesson on Peakscor is original practice in the style of the test it prepares you for. None of it is an official SAT®, ACT® or AP® question, and we are not affiliated with the College Board or ACT.
Our rules
- We never copy or closely paraphrase College Board questions, or questions from any other publisher.
- We never give College Board questions or materials to AI tools, and we never use them as examples to imitate.
- The same goes for the ACT: we never copy or closely paraphrase ACT questions or passages, never give ACT materials to AI tools, and never copy or approximate the score conversion tables ACT uses.
- The structure of the digital SAT and of the ACT is public: their sections, question types, skills and timing. We follow that structure, but the content inside it is ours.
How a question gets written
- Math: most questions come from templates we wrote. Each template builds a new question and computes its answer, so the key is always checked by the math itself.
- Reading and Writing: we use AI tools to help draft passages and questions, modeled only on our own original sample questions. We check questions before they go live, and we audit the question bank regularly for wrong answer keys, questions with two defensible answers, and difficulty labels that are off.
- Lessons: every Learn question is solved blind by a separate reviewer who doesn’t see the answer key. If the reviewer disagrees with the key, or finds two defensible answers, the question is fixed or cut before it goes live.
- ACT: we use AI tools to help write passages and questions, working only from our own original samples and a description of the test we wrote ourselves. Every ACT question is then solved blind by a separate AI reviewer that sees the passage, question and answer choices but never the answer key, and rates every choice. English answers are read back into the passage, Math answers are worked a second way, Science answers are checked against the table or graph as it appears on the page, and Reading answers must be backed by a line of the passage. A question with a disagreement or more than one defensible answer is fixed and checked again, or cut. Nothing ships unchecked.
- AP: historical documents are public domain (for example, the U.S. Constitution) or our own summaries, labeled as summaries. For real past exam questions, we link to the College Board’s AP Central site instead of copying them.
Scores
Scores on Peakscor are estimates based on how you do on our practice questions. They are not official scores and don’t predict an exact result. ACT scores come from our own model, not from ACT conversion tables.
