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.
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.

Form, Structure, and Sense · Lesson 2
Verb tense and form
Tense questions are decided by a time clue in the passage: a date, a phrase such as since 1965 or by the time, or the tense of the other verbs. Find the clue before you look at the choices.
A finished action at a stated past time takes the simple past: In 1869, the railroads met. An action that began in the past and continues to now takes the present perfect, has or have plus a past participle: Since 1965, the river has become colder.
An action completed before another past moment takes the past perfect, had plus a past participle: By the time the telescope launched in 1990, he had argued for it for decades. Present habits and general facts take the present: Each year, the festival draws thousands.
Perfect tenses need the past participle, not the simple past: had begun, not had began; has written, not has wrote.
Every sentence also needs a main verb that could stand as its predicate. An -ing form (concluding) or a to form (to conclude) can't do that job by itself. If the subject has no verb yet, the blank must supply a real one.
| Time clue | Tense | Example |
|---|---|---|
| A finished action at a specific past time: in 1869, last spring | Simple past | met, opened |
| Since, for a span reaching to now | Present perfect | has become, have declined |
| By the time, by then with a past event | Past perfect | had argued, had begun |
| Each year, usually, general facts in a present-tense passage | Present | draws, flows |
| Next year, tomorrow | Future | will open |
Worked example Easy
In 1869, the Central Pacific and Union Pacific railroads at Promontory Summit in Utah Territory, completing the first transcontinental railroad in the United States.
Which choice completes the text so that it conforms to the conventions of Standard English?
- meet
- metAnswer
- will meet
- have met
How to solve it
- Find the time clue: In 1869, a specific time in the past.
- A finished action at a stated past time takes the simple past.
- Met is the simple past.
Why each choice is right or wrong
- A. Incorrect. Meet is present tense, but the event happened in 1869.
- B. Correct. In 1869 places a completed action at a specific past time, so the simple past met is needed.
- C. Incorrect. Will meet is future tense, but the event happened in 1869.
- D. Incorrect. The present perfect have met connects the past to the present and isn't used with a specific past date such as In 1869.
Worked example Medium
The Hubble Space Telescope launched in 1990. By then, the astronomer Lyman Spitzer for a large telescope in space for more than four decades, ever since he first proposed the idea in a 1946 report.
Which choice completes the text so that it conforms to the conventions of Standard English?
- has argued
- argues
- will have argued
- had arguedAnswer
How to solve it
- Find the time clue: By then means by 1990, a moment in the past.
- The arguing happened before that past moment, from 1946 up to 1990.
- An action completed before another past moment takes the past perfect: had argued.
Why each choice is right or wrong
- A. Incorrect. The present perfect has argued describes a span that reaches up to now. This span ended at a past moment, the 1990 launch.
- B. Incorrect. Argues is present tense, but the arguing took place between 1946 and 1990.
- C. Incorrect. Will have argued looks ahead to a future moment, but By then refers to 1990, which is in the past.
- D. Correct. By then points to 1990, and the arguing happened before that past moment, so the past perfect had argued is needed.
