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 digital SAT’s order: 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 use the hardest material throughout.
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.

Rhetorical Synthesis · Lesson 1
What the right answer must include
Once you know the goal, ask what a sentence must contain to accomplish it. Most goals have two or three required parts, and wrong answers usually leave one out.
A difference or a similarity needs both things, the detail being compared, and words that show the relationship: while, whereas, unlike or but for a difference; both, like or also for a similarity. Two facts simply listed side by side with and, with no relationship word, state both facts, but they don't emphasize a difference or a similarity.
A study and its findings needs the study (who did it, or what was studied) and the result. A sentence that only describes what the researcher did, or only reports the numbers, does half the job.
Introduce X to an unfamiliar audience needs a sentence that identifies or defines X, usually with the full name plus what X is: Katherine Johnson, a NASA mathematician. A sentence that uses only a last name, or says the novel without saying which novel or who wrote it, assumes the reader already knows.
A generalization needs a broad statement about a group (many desert plants...), not one or two specific examples. Explain why or explain an advantage needs the reason or the benefit itself, not just a description of the thing.
| The goal says... | The sentence must include | Common near miss |
|---|---|---|
| emphasize a difference between X and Y | X, Y, the compared detail, and a contrast (while, whereas, unlike) | Both facts joined by and, or only one of the two |
| emphasize a similarity between X and Y | X, Y, and what they share (both, like, also) | A difference between them |
| present a study and its findings | Who or what was studied, and the result | The method with no result, or a result with no study |
| introduce X to an unfamiliar audience | X's full name and what X is | A last name only, or the novel with no title or author |
| make a generalization | A broad statement about a group | One or two specific examples |
| explain why, or explain an advantage | The reason or the benefit | A description of what X is or how it works |
| specify when or where | The date or place of the event named in the goal | A date or place for a different event |
Worked example Easy
While researching a topic, a student has taken the following notes:
- Octopuses and squid are both cephalopods, a group of marine animals.
- An octopus has eight arms.
- A squid has eight arms and two longer tentacles.
- Most octopuses and squid can release a cloud of ink to escape predators.
- Most squid live in open water, while many octopuses live on the seafloor.
The student wants to emphasize a similarity between octopuses and squid. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- An octopus has eight arms, while a squid has eight arms and two longer tentacles.
- Most octopuses and squid share a defense: they can release a cloud of ink to escape predators.Answer
- Most squid live in open water, while many octopuses live on the seafloor.
- A squid has eight arms and two longer tentacles.
How to solve it
- The task is a similarity, so the sentence needs both animals and something they have in common, shown with a word such as both, like or share.
- Two choices use while to set the animals against each other. That is the signal of a difference, not a similarity.
- Most octopuses and squid share a defense: they can release a cloud of ink to escape predators names both animals and what they have in common.
Why each choice is right or wrong
- A. Incorrect. The word while sets up a contrast: the squid has two tentacles the octopus lacks. This emphasizes a difference.
- B. Correct. The sentence names both animals and uses share to point to a trait they have in common, the ink defense.
- C. Incorrect. This sentence contrasts where the two animals live, so it emphasizes a difference.
- D. Incorrect. This sentence describes only the squid. A similarity needs both animals.
Worked example Medium
While researching a topic, a student has taken the following notes:
- In 2021, ecologist Priya Raman studied bees in 30 urban gardens in Chicago.
- She counted the bee species that visited each garden over one summer.
- Gardens with native flowering plants attracted an average of 18 bee species.
- Gardens without native plants attracted an average of 7 bee species.
- Native plants are species that occur naturally in a region.
The student wants to present Raman's study and its findings. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- In 2021, ecologist Priya Raman counted the bee species that visited 30 urban gardens in Chicago over one summer.
- Gardens with native flowering plants attracted an average of 18 bee species, while gardens without native plants attracted an average of 7.
- Native plants are species that occur naturally in a region.
- In a 2021 study of 30 Chicago gardens, ecologist Priya Raman found that gardens with native flowering plants attracted more than twice as many bee species as gardens without them.Answer
How to solve it
- The goal has two parts: the study (who studied what) and its findings (what the study showed).
- One choice describes the study but stops before the result. Another reports the result but never says whose study it was or what was studied.
- In a 2021 study of 30 Chicago gardens, ecologist Priya Raman found that gardens with native flowering plants attracted more than twice as many bee species... has both parts. Since 18 is more than twice 7, the comparison matches the notes.
Why each choice is right or wrong
- A. Incorrect. This sentence describes the study well, but it never says what Raman found. It does only half the job.
- B. Incorrect. This sentence reports the findings, but it doesn't present the study: there is no researcher, place or date.
- C. Incorrect. This sentence defines a term from the notes. It doesn't describe the study or its results.
- D. Correct. The sentence presents the study (Raman, 2021, 30 Chicago gardens) and its finding (native plants drew more than twice as many bee species).
