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.

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.

Inferences · Lesson 5
Supported, not strongest
The correct answer is the one the passage supports. It is not the boldest choice, the most exciting one or the one that sounds most important.
Test the strength words. Proves, always, all, only, never and the main cause claim a lot. May, suggests, some and probably claim less. A strong word is wrong whenever the passage doesn't back up that much.
But don't simply pick the most cautious choice. A careful-sounding choice is still wrong if it is off the point or contradicts the passage, and a firm choice is right when the passage really does establish it, as with the fern fossils in the previous lesson.
Before you commit, name what is wrong with each choice you reject. The table below lists the six patterns that cover most wrong answers.
| Pattern | What the choice does | Question to ask |
|---|---|---|
| Too strong | Claims more than the evidence shows: proves, always, every, a cause from a link | Does the passage back up that much? |
| Contradicts the passage | States something a fact in the passage rules out | Does any sentence say otherwise? |
| Repeated premise | Restates a fact already in the passage | Does this add the missing step? |
| Reversed logic | Flips the direction of a cause, a contrast or an only | Does it point the way the passage does? |
| Real world, not the passage | Is plausible in life but never mentioned | Where in the passage is this? |
| Different question | Fits the topic but not the point the blank sets up | Is this what the words before the blank ask for? |
Worked example Medium
When Ines Calder published her novel The Salt Road in 1931, most reviewers dismissed it as confusing. By the 1970s, however, the novel was taught in many university courses, and scholars praised it as an early example of a style that later writers made popular. Calder never revised the novel, and every edition since 1931 has printed the original text. The change in the novel's reputation therefore most likely reflects
Which choice most logically completes the text?
- Calder's decision to revise the novel for a new generation of readers.
- a change in how readers and critics judged the novel rather than a change in the novel itself.Answer
- the fact that The Salt Road is the greatest and most influential novel written in the twentieth century.
- the carelessness of the reviewers who wrote about the novel in 1931.
How to solve it
- What changed: the novel's reputation, from dismissed in 1931 to praised by the 1970s.
- What didn't change: the text. Calder never revised the novel.
- Prediction: if the book stayed the same, the readers' judgment is what changed. That is choice B. Then name each trap: A contradicts the passage, C is too strong, and D is real world, not the passage: it blames the reviewers without any support.
Why each choice is right or wrong
- A. Incorrect. The passage says Calder never revised the novel, so this contradicts it.
- B. Correct. The text was never revised, yet the novel went from dismissed to praised. Since the novel itself stayed the same, the change must lie in how readers and critics judged it.
- C. Incorrect. This is the exciting answer, and far too strong. The passage says scholars praised the novel as an early example of a style, not that it is the greatest and most influential novel of the century.
- D. Incorrect. The passage reports what the 1931 reviewers thought but never says they were careless. This blames them without support.
Worked example Hard
In 2022, a city replaced the streetlights on 40 of its streets with brighter lamps. Over the next year, nighttime car crashes on those streets fell by 18 percent; on streets that kept their old lamps, crashes fell by 3 percent. Traffic engineer Omar Haddad notes that the city upgraded the streets with the most crashes in 2021 first, and that streets with unusually many crashes in one year tend to have fewer the next year even when nothing about them changes. Haddad's point suggests that the data
Which choice most logically completes the text?
- fit the idea that the brighter lamps helped, but part of the drop on the upgraded streets might have happened anyway.Answer
- prove that the brighter lamps caused the entire 18 percent drop in crashes on the upgraded streets.
- show that brighter lamps have no effect on nighttime crashes.
- show that streets that kept their old lamps became more dangerous during the year.
How to solve it
- The result: crashes fell much more on upgraded streets (18 percent) than on the others (3 percent). That looks like the lamps worked.
- Haddad's point: the upgraded streets were the ones with the most crashes in 2021, and such streets tend to have fewer the next year even when nothing about them changes.
- So some of the 18 percent drop may have come without the lamps. But the point doesn't show the lamps did nothing. Prediction: the lamps may have helped, but not all of the drop is clearly theirs. That is choice A.
Why each choice is right or wrong
- A. Correct. The bigger drop on upgraded streets is consistent with the lamps helping. Haddad's point, that high-crash streets tend to have fewer the next year even when nothing about them changes, means part of that drop might have happened without them.
- B. Incorrect. This is the tempting strong answer. Haddad's point is exactly that some of the drop may have happened anyway, so prove and the entire go too far.
- C. Incorrect. This overcorrects. Haddad's point explains how part of the drop could happen on its own; it doesn't show the lamps did nothing.
- D. Incorrect. Crashes on those streets fell by 3 percent, so they did not become more dangerous.
Trap The real-world fact
A choice can be something you know or suspect is true in real life, such as an explanation you have read about elsewhere. If the passage doesn't give you reason to believe it, it isn't the answer. Point to the words that support a choice before you pick it.
Trap The exciting conclusion
Test writers make the boldest choice sound like a breakthrough: proof of a cause, the best of its kind, a rule for everyone. Big claims need big evidence. When the passage gives a careful finding, the answer is usually a careful conclusion.
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.
