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.

Words in Context · Lesson 1
Predict the word from the clues
Every Words in Context blank is decided by something else in the passage: a clue. The passage explains, illustrates, gives a reason for or contrasts with the missing word, and that tells you what the word has to mean.
Use one method every time. First, cover the choices. Second, find the clue: the words that tell you what the blank must mean. Third, predict a word of your own. A plain word or phrase such as careful, small or not finished is fine. Only then look at the choices and pick the one closest to your prediction.
Predicting first protects you from the choices. Every wrong choice is a real word, and many of them sound fine in the sentence by themselves. If you already know you need a word meaning not finished, a word that merely sounds smart won't pull you in.
This lesson covers three kinds of clue. Restatement: a colon, a dash, or a phrase such as that is or in other words that says the same idea again. Example: specific cases, often after for instance, such as or a colon. Cause and effect: because, since, as a result or so ... that, which tie the blank to a reason or a result.
Here is a quick model. In The museum's guide was remarkably : she answered every visitor's question without once checking her notes, the colon restates the idea. A good prediction is well informed.
After you choose, read the whole sentence with your word in the blank. It should agree with the clue, not just sound natural.
Worked example Easy
Ecologist Mariela Ortiz describes the kangaroo rats she studies in the Sonoran Desert as remarkably with water: the animals almost never drink, getting the moisture they need from the dry seeds they eat, and their kidneys lose very little of it.
Which choice completes the text with the most logical and precise word or phrase?
- careless
- economicalAnswer
- familiar
- adventurous
How to solve it
- Cover the choices. The colon after the blank signals a restatement: the second half explains what the first half means.
- The explanation says the rats almost never drink, get their moisture from food, and their kidneys lose very little of it. They use water sparingly. Predict thrifty or careful.
- Economical means using something carefully, without waste. It matches the prediction.
Why each choice is right or wrong
- A. Incorrect. Being careless with water would mean wasting it, the opposite of animals whose kidneys lose very little of it.
- B. Correct. Economical means using something carefully, without waste, which is what the explanation after the colon describes: the rats almost never drink and lose very little water.
- C. Incorrect. Being familiar with water would mean knowing it well, but the rats almost never drink. The explanation after the colon is about saving water, not knowing it.
- D. Incorrect. Nothing after the colon describes taking risks or trying new things. The rats' habits are about saving water, so adventurous has no support.
Worked example Medium
Historian Lena Achterberg relies on the account books of a seventeenth-century Dutch weavers' guild, but she admits that the records are frustratingly . One entry notes a payment without naming who received it, and another mentions a dispute among members but never says what it was about.
Which choice completes the text with the most logical and precise word or phrase?
- inaccurate
- lengthy
- illegible
- incompleteAnswer
How to solve it
- Cover the choices. The sentence after the blank gives two examples of what is frustrating about the records.
- Both examples leave something out: a payment without naming who received it and a dispute whose subject the entry never says. Predict missing information.
- Incomplete matches. Check the close choice: inaccurate would mean the records say something false, but neither example shows a false entry.
Why each choice is right or wrong
- A. Incorrect. This is the close trap. Inaccurate means wrong, but the examples show information left out, not information that is false. Nothing says an entry is mistaken.
- B. Incorrect. Lengthy points the wrong way. The examples complain that the entries say too little, not too much.
- C. Incorrect. Illegible fits the topic of old handwritten records, but the examples are about what the entries leave out, not whether they can be read. Achterberg read them closely enough to find the gaps.
- D. Correct. Both examples describe missing information, a payment without naming who received it and a dispute whose subject is never given, so the records are incomplete.
Trap The word that fits the topic, not the clue
Test writers include a word that belongs with the subject of the passage, such as illegible for old records. It feels right because it matches the topic. Check it against the clue: if the clue is about something else, the topic word is wrong.
Trap The word that only works in its own sentence
Many wrong choices make a good sentence on their own. The records are frustratingly lengthy is a perfectly good sentence; it fails only when you read the examples that follow it. Never judge a choice by the sentence with the blank alone.
Practice
Choose a section, then practice a whole domain or drill a single skill.
Full-length tests
Each test mirrors the digital SAT: 98 questions across four modules, 2 hr 14 min on official timing.
A little harder than the real SAT. These tests can run slightly tougher than test day, which makes them good practice: if you can handle these, the real one should feel easier. No question appears in more than one test, Challenge Tests included.
Challenge Tests Hardest of the hardest
Same 98-question format, but every question is drawn from the toughest SAT material: Challenging-tier math throughout and the hardest reading.
