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 1
Follow the chain to the conclusion
An Inferences passage is an argument with its last step missing. The sentences before the blank set up facts, findings or claims, and the blank asks for what they add up to.
Read it as a chain. For each sentence, ask what job it does: a fact, a finding, a problem, a contrast or someone's claim. Then read the words right before the blank, such as This suggests that or the paintings were therefore most likely. They tell you what kind of conclusion is missing.
Predict before you look. Say the missing step in your own plain words, the way you would finish a friend's sentence. Then find the choice that matches your prediction. A prediction protects you from choices that sound smart but don't follow.
The right answer uses the passage's facts and goes one step past them. It doesn't just repeat something the passage already said, and it never depends on outside knowledge.
Worked example Easy
Botanist Lena Okafor studied a mountain lily that opens its flowers only after dark and closes them again before sunrise. The lily's nectar sits at the bottom of a long, narrow tube, and only insects with very long mouthparts can reach it. Of all the insects active at night in Okafor's study area, only one species of hawkmoth has mouthparts that long. These observations suggest that in the study area,
Which choice most logically completes the text?
- the lily opens its flowers only after dark and closes them again before sunrise.
- this hawkmoth is likely the only insect that can feed on the lily's nectar.Answer
- hawkmoths feed only on flowers that open at night.
- bees and other insects that are active during the day are the lily's most frequent visitors.
How to solve it
- Link 1: the flowers are open only after dark, so only insects active at night can visit them.
- Link 2: the nectar can be reached only by insects with very long mouthparts.
- Link 3: among the night insects, only one species of hawkmoth has mouthparts that long.
- Prediction: put the links together and only that hawkmoth can get the nectar. Choice B says exactly that.
Why each choice is right or wrong
- A. Incorrect. This repeats the passage's first sentence. It is true, but it is a starting fact, not the conclusion the observations lead to.
- B. Correct. The flowers are open only at night, the nectar needs very long mouthparts, and only one species of hawkmoth among the night insects has them. Together, these facts point to that hawkmoth as the only insect that can feed there.
- C. Incorrect. The passage is about which insects can feed on this lily, not about everything hawkmoths eat. Nothing says what else hawkmoths feed on, so only goes beyond the evidence.
- D. Incorrect. The flowers close before sunrise, so daytime insects can't reach the nectar at all. The passage points away from this choice.
Worked example Medium
Art historian Priya Raman studies the Norwegian painter Elsa Lindqvist, who ground her own paints by hand until 1902. The blue pigment Lindqvist made for her skies faded noticeably within a few decades. In 1902, she switched to a ready-made blue paint that chemists have shown does not fade. Several of Lindqvist's seascapes are undated, but their skies are still a strong, unfaded blue today. Raman concludes that these seascapes were most likely
Which choice most logically completes the text?
- painted before 1902, when Lindqvist still ground her own paints.
- restored at some point by later artists who repainted the faded skies with new blue paint.
- painted after Lindqvist switched to ready-made blue paint in 1902.Answer
- among the most valuable paintings that Lindqvist ever made.
How to solve it
- Sort the facts. Before 1902: homemade blue that faded noticeably within a few decades. From 1902: ready-made blue that does not fade.
- The clue: the undated skies are still a strong, unfaded blue today, but the homemade blue faded noticeably within a few decades.
- Prediction: skies that never faded were painted with the paint that doesn't fade, so the seascapes come from 1902 or later. That is choice C.
Why each choice is right or wrong
- A. Incorrect. This reverses the logic. Paintings from before 1902 would have used the homemade blue, which faded within a few decades, so their skies would not still look unfaded.
- B. Incorrect. Restoration could make old skies look new in real life, but the passage never mentions it. Raman's conclusion has to come from the facts given, and they point to the date of the paint.
- C. Correct. The homemade blue faded noticeably within a few decades, and the 1902 paint does not fade. Skies that are still a strong, unfaded blue today fit only the later paint.
- D. Incorrect. The passage says nothing about the paintings' value. This answers a different question from the one the facts about paint and fading set up.
Trap The repeated premise
A choice that only restates a fact from the passage is accurate, which makes it tempting. But the blank asks for what the facts lead to. If a choice adds nothing beyond a sentence you have already read, it doesn't complete the reasoning.
Trap The answer to a different question
Some choices are about the right topic but not the right point. If a passage builds toward when something happened, a choice about why it matters or how good it is answers a question nobody asked. Check your choice against the words just before the blank.
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.
