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 4
Main ideas in literary passages
Some passages come from novels, short stories, plays or poems. On the test, these excerpts come from published works. In this course they are written for practice, but the questions work the same way.
In a literary passage, the main idea is usually about a character: what they feel, want or realize, or how they change over the excerpt. In a poem, it may be about the speaker's view of a person, place or memory.
Writers often show feelings instead of naming them. Watch what characters do, say and notice. A character who answers every question with a single word may be upset, distracted or holding something back, even if the narrator never says so. Let the rest of the excerpt tell you which.
Then apply the same tests as before. The right answer covers the whole excerpt, not one vivid moment. Its feelings are as strong as the text shows and no stronger. And it adds no reasons or backstory the text doesn't give.
Worked example Easy
The following text is from a story written for this course, set on a farm in the early 1900s.
Every morning that spring, Clara walked to the edge of the north field before breakfast and stood looking at the bare rows. Her father said the seed would come up when it was ready and that staring at the dirt would not hurry it. Still, she went. On the eleventh morning she saw a faint green line along the second row, and she ran back to the house so fast that she forgot to close the gate behind her.
Which choice best states the main idea of the text?
- Clara waits eagerly for the seeds to sprout and is excited when they finally do.Answer
- Clara's father is annoyed that Clara spends her mornings in the field instead of doing chores.
- Clara learns from her father that seeds can't be hurried, so she stops visiting the field.
- Clara forgets to close the gate, and animals get into the north field.
How to solve it
- Watch what Clara does: she visits the field every morning, keeps going even after her father's comment, and runs home when the sprouts appear.
- Those actions show eagerness and then excitement, even though the narrator never names either feeling.
- The first choice covers the whole excerpt, from the waiting to the moment the seeds come up.
Why each choice is right or wrong
- A. Correct. Clara goes to the field every morning, keeps going (Still, she went), and runs home so fast that she forgot to close the gate once the seeds sprout. That shows eager waiting and then excitement.
- B. Incorrect. Her father says only that staring at the dirt would not hurry it. The passage never mentions chores or shows him annoyed, so this adds a feeling and a detail the text doesn't give.
- C. Incorrect. Still, she went shows that she keeps visiting the field despite what her father says. This choice contradicts the passage.
- D. Incorrect. Clara does forget the gate, but the passage never says animals got in. This adds an outside event to one small detail.
Worked example Medium
The following text is from a story written for this course, set in a city in the 1920s.
Mr. Abernethy had kept the corner bookshop for thirty years and did not care for the new lending library down the street. Free books, he told his customers, taught people that books were worth nothing. Yet when a boy came in one afternoon asking for a sea story that the library had no copy of, Mr. Abernethy found one on a high shelf, wrapped it in brown paper and told the boy to bring it back when he was finished. He did not write the boy's name in any ledger.
Which choice best states the main idea of the text?
- Mr. Abernethy believes the new lending library down the street will soon force his corner bookshop to close.
- Despite criticizing free lending, Mr. Abernethy quietly lends a book to a boy himself.Answer
- Mr. Abernethy refuses to help a boy who had first tried the lending library.
- Mr. Abernethy keeps a careful record of every book he sells or lends.
How to solve it
- Notice the turn word Yet. Before it, Mr. Abernethy complains that free books teach people that books are worth nothing. After it, he lends a book for free.
- The last sentence adds that he keeps no record of the loan, which makes the act quiet and trusting.
- The main idea joins both halves: what he says and what he does.
Why each choice is right or wrong
- A. Incorrect. He did not care for the library and criticizes free books, but the passage never says he fears his shop will close. This adds a reason the text doesn't give.
- B. Correct. Before Yet, he says free books teach that books were worth nothing. After it, he lends the boy a book and did not write the boy's name in any ledger. The passage turns on the gap between his words and his action.
- C. Incorrect. This reverses what happens. He finds the book, wraps it and lends it to the boy.
- D. Incorrect. This contradicts the last sentence: He did not write the boy's name in any ledger.
Trap One vivid moment
Literary passages often contain one striking image or action, such as a forgotten gate or a book wrapped in brown paper. A choice built around that moment feels right because it is memorable. Ask whether it explains the whole excerpt, or only one sentence of it.
Trap Too strong a feeling, or a story behind the story
If a character only hesitates, and the text shows nothing more, furious or terrified is too strong. If a character is distracted, the text may never say why, and a choice that supplies the reason (a secret fear, an old quarrel) adds something the passage doesn't give. Pick the feeling the evidence shows, at the strength it shows 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.
