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.

Text Structure and Purpose · Lesson 2
Overall structure: the moves in order
A structure question asks how the passage is built: which moves it makes and in what order. The choices read like short outlines: It describes a view, then presents evidence against it.
Map the passage before you read the choices. Give each sentence, or each group of sentences, a label of two or three words: background, researcher's claim, evidence, exception, conclusion. Then join the labels with then.
Check every choice against your map, piece by piece. The right answer covers every main move, in the same order, with verbs of the right strength, and no extra move the passage doesn't make. One wrong piece makes a choice wrong, even if the rest matches perfectly.
Turn words help you find the moves. However, but and yet often start a challenge or an exception. For example usually starts an illustration. As a result and so often start an effect or a conclusion.
Worked example Easy
Most plants make their own food from sunlight, using the green pigment in their leaves. The ghost plant, a white flowering plant of shady forests, has no green pigment and cannot use sunlight at all. Instead, it takes its food from fungi in the soil. Those fungi, in turn, get their food from the roots of nearby trees, so the ghost plant is ultimately fed by the trees around it.
Which choice best describes the overall structure of the text?
- It describes how the ghost plant gets its food, then explains why most plants need sunlight.
- It states how most plants get food, then presents an exception and traces its food source.Answer
- It introduces a plant that lacks green pigment, then argues that this plant harms nearby trees.
- It compares the ghost plant with fungi, then explains how fungi feed the trees in a forest.
How to solve it
- Label each sentence. 1: how most plants get food. 2: a plant that can't do that. 3: where it gets food instead, fungi. 4: where the fungi get theirs, trees.
- Join the labels: general rule, then an exception, then where the exception's food comes from.
- Only the second choice has those moves in that order and nothing more.
Why each choice is right or wrong
- A. Incorrect. The moves are in the wrong order. The passage starts with how most plants get food and only then turns to the ghost plant, and it ends by tracing the ghost plant's food back to the trees, not by returning to other plants.
- B. Correct. The first sentence gives the general rule, the second introduces the ghost plant as an exception, and the last two trace its food from fungi back to the roots of nearby trees.
- C. Incorrect. The passage says the ghost plant is fed by the trees around it, but it never says the plant harms them and makes no argument. This adds a step the text doesn't have.
- D. Incorrect. This reverses the food chain. The passage says the fungi get their food from the roots of nearby trees, not that the fungi feed the trees.
Worked example Medium
Sociologist Amara Lindqvist argues that public libraries do more than lend books: in many small towns, they are the main indoor gathering place. In a survey of 85 towns with fewer than 5,000 residents, she found that the library hosted more community meetings each year than any other public building in 61 of them. Lindqvist acknowledges, though, that her survey covered only towns in the Midwest, where winters are long, and that libraries may play a smaller role where people can gather outdoors for much of the year.
Which choice best describes the overall structure of the text?
- It presents survey results about small-town libraries, then states a claim that those results contradict.
- It makes a claim about libraries, offers evidence for it, and then rejects the claim because of where the survey was done.
- It describes meetings held in Midwest libraries, then explains why they are more popular in winter than in summer.
- It makes a claim about libraries, offers evidence for it, and then notes a limit on that evidence.Answer
How to solve it
- Label the moves. Sentence 1: Lindqvist's claim. Sentence 2: survey evidence for it. Sentence 3, which begins Lindqvist acknowledges, though: a limit on how far the survey reaches.
- Map: claim, then evidence, then a limit. Note the strength of the last move. She acknowledges a limit; she doesn't drop her claim.
- The last choice matches every move at the right strength. The second choice gets the first two moves right but makes the last one far too strong.
Why each choice is right or wrong
- A. Incorrect. The order and the relationship are both wrong. The claim comes first, and the survey supports it: the library hosted the most meetings in 61 of them.
- B. Incorrect. The first two moves match, but the last is too strong. Lindqvist acknowledges that her survey covered only the Midwest. Admitting a limit is not rejecting the claim.
- C. Incorrect. The passage never compares winter and summer meetings. It mentions long winters only to show why the survey's reach is limited.
- D. Correct. The passage states Lindqvist's claim, supports it with her survey of 85 towns, and ends by noting that her survey covered only towns in the Midwest, so the claim may not hold everywhere.
Trap Right moves, wrong order
Structure choices often reuse the passage's own moves in a different order: presents evidence, then states a claim when the claim came first. Every piece sounds familiar, so the choice feels right. Check the order against your map, one then at a time.
Trap The extra step
A choice can match every move and then add one more: and then proposes a solution, and then explains why, and then rejects the claim. If you can't point to the sentence that makes that move, the choice is wrong, however well the rest fits.
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.
