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.

Central Ideas and Details · Lesson 2
Find the turn: where the main idea often lives
Many SAT passages are built around a turn. They open with what people used to think, what researchers have long assumed or what seems true at first. Then a word such as however, but or yet, or a phrase such as recent work suggests or a new study challenges this view, changes direction.
When a passage turns, the main idea is usually what comes after the turn: the new finding or the writer's own claim. The view before the turn is there to be questioned. That makes a choice that simply restates the old view one of the most common traps.
Some turns have no signal word. A sentence such as A new study paints a different picture or Historian X draws another conclusion does the same job. Read for any sentence that pushes against what came before.
Not every turn is a full reversal. Notice how far the passage goes. Phrases such as partly challenges, refines or accepts part of that view mean the new claim adds to or limits the old one instead of replacing it. A choice that says the old view was completely wrong goes further than the passage does.
Worked example Easy
Field guides have long described the banded sand runner, a small desert lizard, as active only during the day. However, herpetologist Joaquín Ruiz placed motion-triggered cameras near the lizards' burrows and recorded them hunting on warm nights, sometimes for hours. Ruiz suggests that the species' daily routine is more flexible than the guides describe.
Which choice best states the main idea of the text?
- Ruiz's recordings suggest that the banded sand runner is not strictly a daytime animal.Answer
- The banded sand runner is active only during the day.
- Motion-triggered cameras are the best tool for studying desert lizards.
- Most desert lizards, not just the banded sand runner, hunt at night whenever the weather is warm enough.
How to solve it
- Find the turn: However at the start of the second sentence.
- Before the turn is the old view: the lizard is active only by day. After the turn is Ruiz's evidence (night hunting on camera) and his claim that its routine is more flexible.
- The main idea is the claim after the turn, which is the first choice. The second choice is the view before the turn.
Why each choice is right or wrong
- A. Correct. After the turn word However, the passage gives Ruiz's evidence of night hunting and his conclusion that the species' routine is more flexible than the guides describe.
- B. Incorrect. This is the field guides' view, the one the passage questions. Ruiz's cameras recorded the lizards hunting on warm nights, which contradicts it.
- C. Incorrect. The passage says Ruiz used cameras but never compares them with other tools. The best tool is an outside claim.
- D. Incorrect. Ruiz studied one species. A claim about most desert lizards is far broader than the passage.
Worked example Medium
Historians have often assumed that ordinary households in the port town of Varnholm ate a dull diet of bread and porridge during the 1600s. Historian Lucia Ferrante's study of household account books from the period complicates that picture. The accounts record regular purchases of fresh fish, spices such as pepper and cinnamon, and fruit brought by ship from distant ports, even in families of modest means.
Which choice best states the main idea of the text?
- In the 1600s, ordinary households in Varnholm ate a dull diet of bread and porridge.
- In the 1600s, most of Varnholm's ordinary households grew or caught their own food, including fruit and fish, rather than buying it at markets.
- In the 1600s, families of modest means in Varnholm bought more fresh fish, spices and imported fruit than the town's wealthy families did.
- Ferrante's study of account books suggests that ordinary Varnholm households ate a more varied diet than historians have often assumed.Answer
How to solve it
- There is no however here. The turn is the second sentence: Ferrante's study complicates that picture.
- Before the turn: historians' assumption of a dull diet. After it: account books full of fish, spices and fruit, even for modest families.
- Summary: Ferrante's records show ordinary households ate a more varied diet than historians assumed. That is the last choice.
Why each choice is right or wrong
- A. Incorrect. This is the assumption the passage questions. Ferrante's study complicates that picture, so the passage does not present this as true.
- B. Incorrect. The account books record purchases, and the passage never says how much food households grew or caught themselves. This is an outside claim.
- C. Incorrect. Even in families of modest means says these families also bought such foods. It doesn't say they bought more than wealthy families. The choice distorts the passage into a comparison it never makes.
- D. Correct. The turn comes with complicates that picture, and the account books, with their fish, spices and fruit even in families of modest means, are the evidence for a more varied diet than historians assumed.
Trap The view the passage argues against
When a passage opens with what people assumed, believed or long described, a choice will often restate that view almost word for word. It matches the first sentence closely, so it feels right. Check whether the rest of the passage supports that view or pushes against it. If a turn follows, the old view is not the main idea.
Trap Turning further than the passage does
A passage can disagree with an earlier view only in part. If it says the new evidence refines, adds to or partly challenges the old view, a choice saying the old view was simply wrong, or that the opposite is true, goes too far. Match how much the passage changes, not just which way it turns.
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.
