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.

Inferences · Lesson 4
Combining two facts
Some passages give two facts in different sentences, and the conclusion appears only when you put them together. If every member of a group has a feature and this thing belongs to the group, then this thing has the feature. If an event happened after one date and before another, it falls between them.
Look for a detail that seems to matter little on its own, such as a date, a color or a single word like only. It is often one half of the pair.
*Read only and if in the right direction. A ticket is valid only if it is stamped* means an unstamped ticket is not valid. It does not mean every stamped ticket is valid. Wrong choices often flip a statement like this around.
A choice that uses just one of the two facts is often half right, which is what makes it tempting. The answer has to fit both.
Worked example Easy
Paleobotanists have found fossils of a certain extinct fern only in rock layers that formed between 60 million and 55 million years ago. While surveying a cliff, geologist Ruth Adeyemi found fossils of this fern in one of the cliff's rock layers. Based on these two facts, the layer most likely formed
Which choice most logically completes the text?
- more than 60 million years ago, in an earlier period.
- between 60 million and 55 million years ago.Answer
- less than 55 million years ago, in a later period.
- at the same time as every other layer in the cliff.
How to solve it
- Fact 1: this fern's fossils turn up only in layers that formed between 60 and 55 million years ago.
- Fact 2: Adeyemi found the fern's fossils in one layer of the cliff.
- Combine them: that layer belongs to the only time span where the fossils appear. That is choice B.
Why each choice is right or wrong
- A. Incorrect. The fern's fossils have been found only in layers from 60 to 55 million years ago, not in older ones.
- B. Correct. Fossils of the fern appear only in layers that formed between 60 and 55 million years ago, and this layer contains them, so it most likely formed in that span.
- C. Incorrect. Layers younger than 55 million years have never been found to contain this fern, so this contradicts the first fact.
- D. Incorrect. The passage dates only the layer with the fossils. It says nothing about the other layers, which could be older or younger.
Worked example Medium
The seeds of a rare forest orchid cannot sprout unless a particular soil fungus is present, so the orchid grows only in soil that contains the fungus. In a survey of Valley Ridge, botanists found the fungus throughout the valley's soil but did not find a single orchid. Taken together, these facts suggest that
Which choice most logically completes the text?
- the fungus is probably not present in Valley Ridge after all.
- the orchid's seeds can sprout without the fungus in some kinds of forest soil.
- wherever the fungus grows in the soil, the orchid will also be found growing there.
- the fungus alone is not enough to make the orchid grow in a place.Answer
How to solve it
- Fact 1: the orchid grows only where the fungus is. So no fungus means no orchid.
- Fact 2: Valley Ridge has the fungus everywhere but no orchids.
- Combine them: the fungus is needed, but having it doesn't guarantee orchids. Something else is needed too. That is choice D.
Why each choice is right or wrong
- A. Incorrect. The botanists found the fungus throughout the valley's soil, so this contradicts the survey.
- B. Incorrect. The passage says the seeds cannot sprout unless the fungus is present, so this contradicts the first fact.
- C. Incorrect. This flips only. The orchid grows only where the fungus is, which doesn't mean it grows wherever the fungus is, and Valley Ridge is a place with the fungus and no orchids.
- D. Correct. The orchid needs the fungus, yet a valley full of the fungus has no orchids. The fungus is necessary but not sufficient on its own.
Trap The flipped only
X happens only where Y is present means no Y, no X. Wrong choices turn it into wherever Y is present, X happens. Before choosing, say the statement both ways and check which one the passage actually gives you.
Trap The half answer
When a passage gives two key facts, one wrong choice usually fits the first fact and ignores the second. It feels right because part of it is. Check every choice against both facts.
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.
