Built like the real test

  • The real structure. Two Reading and Writing modules of 27 questions in 32 minutes each, a 10-minute break, then two Math modules of 22 questions in 35 minutes each.
  • A Bluebook-style screen. The timer, Mark for Review, answer eliminator, highlighter, reference sheet and a built-in graphing calculator work the way they do on test day.
  • The harder Module 2, every time. On the real test a strong Module 1 sends you to a harder Module 2. Margin always gives you that one, because it’s the only route to a top score.
  • Written from scratch. Every passage, data set and problem is original, tagged with College Board’s own domain and skill names, and checked by solving it again from scratch.
  • A full report. An estimated score from 400 to 1600, your time on every question, the misses you never marked, and a Redo bank that brings your misses back.

Two sample questions

Reading and Writing · Central Ideas and Details

Urban ecologists have documented that many bird species sing at higher pitches in cities than members of the same species do in rural areas, a shift usually explained as a response to low-frequency traffic noise. But ecologist Kwame Asante points out that cities differ from forests in more than noise: dense buildings reflect sound, and hard surfaces carry high frequencies farther than leaf-covered ground does. In a study of great tits in twelve European cities, Asante found that song pitch was more strongly associated with the density of tall buildings than with traffic noise levels, suggesting that the acoustic structure of the urban environment, and not merely its loudness, may shape birdsong.
Which choice best states the main idea of the text?
  1. AAsante's research shows that traffic noise has no effect on the pitch of urban birdsong.
  2. BGreat tits in cities sing at higher pitches than great tits in forests because buildings block low-frequency sounds.
  3. CUrban ecologists have overestimated the amount of traffic noise in European cities.
  4. DAsante's research suggests that a commonly accepted explanation for higher-pitched urban birdsong may be incomplete.
Show the answer
Answer: DAsante adds a factor (“not merely its loudness”) rather than replacing noise outright. D captures that. A overstates (“no effect”); B states a mechanism the text never claims (“block”); C is unsupported.

Questions

Are the tests really free?

Yes. All five tests, their PDFs and every explanation are free, with no account and no sign-up.

Where is my progress saved?

In your browser on the device you use. Nothing is sent to a server, so clearing your browser data clears your history.

How accurate is the score?

Each full test gets an estimated score made by converting your raw score in each section with a fixed table. College Board scores the real test with a statistical model nobody outside College Board can reproduce, so treat it as a close estimate.

Can I take them on paper?

Every test comes as a PDF laid out like a paper booklet, with an answer sheet and explanations. Paper mode lets you write on it in the browser and time each module.

Ready for Test 1?

Set aside 2 hours and 14 minutes, or start with a single module.
