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.
Official timing, extended 1.5× time, or untimed, on every test, including the free ones. Extended time allows 48 minutes for each Reading & Writing module and about 52 for each Math module. Untimed removes the clock so you can focus on accuracy.
A quick run with three hearts. Each right answer builds your streak: the questions get harder as it grows, and your points multiply (×2 from three in a row, ×3 from six). A miss costs a heart and drops you back to easy. Best is your longest streak.

Transitions · Lesson 1
Contrast, cause, continuation and example
Four families cover most Transitions questions. Each has a quick test: say the two sentences to yourself with a plain word between them and hear whether it makes sense.
Contrast (However,, By contrast,, Nevertheless,, Instead,): the test word is but. The second idea goes against the first, breaks an expectation, or describes a different subject that behaves differently. By contrast and In contrast usually compare two different things. Instead signals a replacement: something did not happen or was rejected, and something else took its place.
Cause and effect (Therefore,, As a result,, Consequently,, Thus,): the test word is so. The sentence with the blank must follow from the sentence before it, either as a result it causes or as a conclusion it supports. If the sentence with the blank simply explains why the earlier sentence is true, rather than drawing a conclusion from it, the direction is backward and a cause-and-effect transition is wrong.
Continuation or addition (Moreover,, Furthermore,, In addition,): the test words are and also. The new sentence adds a further point that points the same way. Similarity (Similarly,, Likewise,) is a close cousin with a stricter rule: it needs a second, parallel case, usually a different subject doing the same kind of thing.
Example (For example,, For instance,): the test words are here is one case. The earlier text, usually the sentence right before the blank, makes a general claim, and the sentence with the blank gives a specific case that fits it. A specific case that breaks the general claim is a contrast, not an example.
Worked example Easy
The Dead Sea, a salt lake in the Middle East, is almost ten times saltier than typical ocean water. All that dissolved salt makes its water much denser than fresh water or ordinary seawater. swimmers float on its surface with almost no effort, and visitors often pose for photos lying back in the water while holding a book or newspaper.
Which choice completes the text with the most logical transition?
- Consequently,Answer
- Nevertheless,
- For example,
- In other words,
How to solve it
- Cover the choices. The sentence before the blank says the salt makes the water very dense.
- The sentence with the blank says swimmers float easily. Dense water, so people float: this is cause and effect.
- The cause-and-effect choice is Consequently,.
Why each choice is right or wrong
- A. Correct. Easy floating is a result of the water's high density, so the sentence follows from the one before it.
- B. Incorrect. Nevertheless means "despite that," but swimmers float because of the dense water, not in spite of it.
- C. Incorrect. Floating swimmers are not a specific case of dense water. They are an effect of it.
- D. Incorrect. The sentence does not reword the claim about density. It adds a new idea: what that density does to swimmers.
Worked example Medium
Most frogs lay their eggs in water, where the eggs hatch into swimming tadpoles that later transform into adults. the coquí frogs of Puerto Rico lay their eggs on land, and the young skip the tadpole stage entirely, hatching as tiny, fully formed froglets.
Which choice completes the text with the most logical transition?
- Similarly,
- For instance,
- By contrast,Answer
- As a result,
How to solve it
- Cover the choices. The first sentence states a general pattern: most frogs lay eggs in water and have tadpoles.
- The second sentence describes frogs that break that pattern: eggs on land, no tadpoles. The plain word is but.
- The coquí is a specific frog, which makes For instance, tempting. But a specific case that goes against a general claim is a contrast, not an example. The answer is By contrast,.
Why each choice is right or wrong
- A. Incorrect. Similarly would mean coquí frogs develop the same way as most frogs, but the passage says they skip the tadpole stage.
- B. Incorrect. An example would have to fit the general claim. The coquí does the opposite of what most frogs do, so it is not an instance of that pattern.
- C. Correct. The second sentence sets the coquí frogs against the pattern described in the first: eggs on land and no tadpole stage.
- D. Incorrect. The way most frogs reproduce does not cause the coquí to reproduce differently. The two sentences compare two kinds of frogs; they don't connect a cause with its effect.
