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.

Central Ideas and Details · Lesson 3
Detail questions: answer from the words on the page
Detail questions ask about one piece of information. They often begin According to the text, or Based on the text, what is true about... You don't need the main idea for these. You need the right sentence, read carefully.
Use the same steps every time. Find the sentence or two that the question points to. Reread them, even if you think you remember. Put the answer in your own words. Then pick the choice that says the same thing.
The right answer says the same thing as the passage, sometimes in different words and sometimes in nearly the same words. Wrong answers often reuse some of the passage's words but change one thing, or add something the passage never says. Check each choice against the sentence for five things:
The group: is it about the same people, animals or things? The cause: does it give the reason the passage gives? The degree: some versus most, less versus none, may versus does. The direction: more versus fewer, and which thing causes which. The source: does the passage say it at all?
Worked example Easy
In a study of city parks, ecologist Mina Sato compared ponds bordered by tall grasses with ponds bordered by mowed lawn. The ponds with tall grasses held about three times as many dragonfly species. Sato explains that adult dragonflies perch on tall stems while hunting, and young dragonflies use the stems to climb out of the water when they change from swimming young into flying adults.
According to the text, why did the ponds bordered by tall grasses hold more dragonfly species?
- The tall stems give adult dragonflies places to perch while hunting and give young dragonflies a way to climb out of the water.Answer
- Mowed lawns release chemicals into nearby ponds that harm young dragonflies before they can change into flying adults.
- Tall grasses hide dragonflies from the birds that hunt them, so more kinds of dragonflies survive around those ponds.
- Dragonflies lay more eggs in city ponds than in other bodies of water.
How to solve it
- The question asks why, so find the sentence that gives Sato's explanation: the last one.
- In your own words: the stems are perches for hunting adults and ladders for young dragonflies leaving the water.
- The first choice says exactly that. Each other choice gives a reason the passage never mentions.
Why each choice is right or wrong
- A. Correct. This paraphrases Sato's explanation: adults perch on tall stems while hunting, and young dragonflies use the stems to climb out of the water.
- B. Incorrect. The passage never mentions chemicals from lawns. This is an outside claim that offers a different cause.
- C. Incorrect. Birds are never mentioned. This gives a cause the passage doesn't state.
- D. Incorrect. The passage compares two kinds of ponds, not ponds with other bodies of water, and it says nothing about egg laying.
Worked example Medium
Economist Farah Lindgren studied a city program that offered free bus passes to residents over age 65. In the program's first year, older residents took about 40 percent more bus trips than they had the year before. The increase was largest among residents who did not own cars, and many of the new trips were to grocery stores and medical appointments rather than to social events.
According to the text, what did Lindgren find about the program's first year?
- Older residents who did not own cars showed the largest increase in bus trips.Answer
- Older residents took about 40 percent more bus trips to social events.
- Residents of all ages took about 40 percent more bus trips.
- Many older residents who owned cars stopped driving and began taking the bus instead.
How to solve it
- All four choices are about the first year, so check each against the second and third sentences.
- The passage gives three findings: about 40 percent more trips by older residents, the biggest increase among those without cars, and many new trips to groceries and doctors rather than social events.
- The first choice matches the second finding exactly. The second and third choices each change one thing (the kind of trip, the group), and the fourth adds something the passage never says about car owners.
Why each choice is right or wrong
- A. Correct. The passage says The increase was largest among residents who did not own cars.
- B. Incorrect. The 40 percent figure is for bus trips in general, and the passage says many new trips were to stores and appointments rather than to social events. This choice changes the kind of trip.
- C. Incorrect. The passes and the 40 percent increase concern residents over age 65. Residents of all ages changes the group.
- D. Incorrect. The passage says nothing about car owners giving up driving. It mentions car ownership only to say the increase was largest among people who did not own cars.
Trap Familiar words, changed meaning
A wrong choice can reuse the passage's exact words and still say something the passage doesn't. It may attach a finding to the wrong group, give it the wrong cause, or run the relationship backward: the birds follow the herds when the passage says the herds follow the birds. Familiar words are not proof. Check who does what to whom.
Trap Some becomes most
Watch the strength of every claim. Some is not most, often is not always, slowed is not stopped, and may is not does. A choice that turns up the degree, even slightly, is not what the passage says.
Trap True in the world, absent from the text
A choice can be a reasonable fact about the topic and still be wrong, because the question asks what the text says. If you can't point to the words in the text that support it, don't pick it.
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.
