Free diagnostic test

Find out why you're missing points.

Not just a score: which skills to learn, in what order, so your plan fixes the right thing first.

• 1

  About 15–30 questions

  The test adapts as you go: get one right and the next is harder, miss one and we check the basics underneath it.

• 2

  No timer

  Take the time you need. Keep Desmos or your calculator handy, just like on the real test.

• 3

  Not sure? Say so

  An “I don't know” button tells us more than a random guess. (On the real SAT, always guess.)

• 4

  Your results, right away

  See which skills to learn first, which mistakes keep repeating, and what you can skip.
