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.

Command of Evidence (Quantitative) · Lesson 5
Wrong answers that look right
Wrong choices in these questions follow a small set of patterns. Once you can name them, you can cross them out quickly.
Test 1: Is it accurate? Check every number and word against the table or graph. This removes choices that misread units or scale (45 instead of 4,500), swap groups or columns, reverse a relationship (rose when the data fell), or overgeneralize: they say every or always when one case breaks the pattern, or turn averages into a statement about every individual.
Test 2: Is it on target? Compare the choices still standing with your checklist from the claim. This removes choices that are true but off target: the wrong group, the wrong year, a snapshot when the claim is about change, or half of a two-part comparison.
Some choices fail both tests. Running the accuracy test first often clears out two choices quickly, but the choice you keep must still match the claim exactly.
| Pattern | What it looks like | Catch it by |
|---|---|---|
| Off target | accurate numbers about the wrong group, year or comparison | checking the choice against the claim's checklist |
| Swapped or reversed | the right numbers attached to the wrong group, or a change in the wrong direction | matching each number to its row, column, bar or line |
| Overgeneralized | every, always or all when one case breaks the pattern, or a claim about individuals from averages | looking for the one case that breaks it |
| Units or scale | a number without its unit, or a percent read as a count | reading the title, headers and axis titles first |
| Snapshot or half | one time for a claim about change, or one group for a comparison | asking whether every side of the claim is there |
Worked example Medium
Adults Who Signed Their Names on Marriage Records in Three Towns (%)
| Town | 1850 | 1880 |
|---|---|---|
| Kestrel | 48 | 71 |
| Ashgrove | 55 | 63 |
| Thane | 39 | 74 |
Historians often use signatures on marriage records to estimate how many adults could write. Historian Adaeze Nwosu argues that free village schools, which opened in all three towns after 1855 but were most numerous in Thane, had their largest effect there. The marriage records are consistent with this argument:
Which choice most effectively uses data from the table to complete the statement?
- in 1880, Thane had the largest share of adults who signed their names, 74%.
- in Thane, the share of adults who signed their names rose by 35 percentage points, from 39% to 74%, compared with 23 points in Kestrel and 8 points in Ashgrove.Answer
- in every town, more than half of adults signed their names in both 1850 and 1880.
- in Thane, the share of adults who signed their names fell from 74% to 39%.
How to solve it
- Test 1, accuracy: choice C fails, because in 1850 only 48% in Kestrel and 39% in Thane signed their names. Choice D reverses Thane's change. Both are out.
- Test 2, on target: largest effect is about change after the schools opened, so the choice needs Thane's rise compared with the other towns' rises. Choice A is accurate but gives only 1880, a snapshot.
- Choice B gives the change in all three towns: 74 − 39 = 35 points in Thane, 71 − 48 = 23 in Kestrel and 63 − 55 = 8 in Ashgrove.
Why each choice is right or wrong
- A. Incorrect. It's accurate, but it's a snapshot. Largest effect is about change after the schools opened, and a high 1880 share doesn't show how much Thane improved; Kestrel's 1880 share (71%) was nearly as high.
- B. Correct. The schools' effect shows up as change from 1850 to 1880: 74 − 39 = 35 points in Thane, 71 − 48 = 23 in Kestrel and 63 − 55 = 8 in Ashgrove. Thane's rise was the largest.
- C. Incorrect. This overgeneralizes. In 1850, only 48% of adults in Kestrel and 39% in Thane signed their names, less than half in each town.
- D. Incorrect. This reverses the change. Thane's share was 39% in 1850 and 74% in 1880, so it rose.
Worked example Hard
In 2017, the Varga Art Museum stopped charging admission on weekdays but kept charging for weekend visits. Museum director Zsófia Bende reports that within a few years, the change closed the gap between weekday and weekend attendance.
Which choice most effectively uses data from the graph to support Bende's claim?
- Average weekday attendance was 5 visitors per day in 2016, compared with 12 on weekends, but by 2019 both averaged 12 visitors per day.
- Average weekend attendance was 1,200 visitors per day in both 2014 and 2020.
- Average weekday attendance was at least as high as average weekend attendance in every year from 2017, when weekday admission became free, through 2020.
- Average weekday attendance was 500 visitors per day in 2016, compared with 1,200 on weekends, but by 2019 both averaged 1,200 visitors per day.Answer
How to solve it
- The claim is about a gap closing, so the choice needs both lines: weekdays well below weekends before the change, then equal later.
- Read the y-axis title first: visitors are in hundreds. A weekday value of 5 means 500 visitors per day, and 12 means 1,200.
- Accuracy test: choice A drops the hundreds, and choice C fails in 2017 and 2018. On-target test: choice B is accurate but covers only weekends. Choice D is left.
Why each choice is right or wrong
- A. Incorrect. The y-axis is in hundreds, so 5 and 12 mean 500 and 1,200 visitors per day. The pattern is right, but the numbers misstate the data.
- B. Incorrect. It's accurate, but it describes only weekends. The claim is about the gap between weekday and weekend attendance.
- C. Incorrect. This overgeneralizes. In 2017 weekdays averaged 800 visitors per day and weekends 1,200, and in 2018 it was 1,000 versus 1,300, so weekdays were lower in both years.
- D. Correct. In 2016, before the change, weekdays (500) trailed weekends (1,200) by 700 visitors per day; by 2019 both averaged 1,200, so the gap had closed within a few years.
Trap Words that go beyond the data
Every, always, all and never are accurate only if no case breaks the pattern, so test them against every row or point. Also watch for choices that turn averages into statements about every individual, or that describe years the data don't cover.
Trap The almost-right numbers
A choice can use the right digits and still misstate the data: a value in hundreds read as ones, a percent read as a count, or two values swapped between groups. Each of these makes the choice inaccurate, however close it looks.
Practice

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.
