Practice that turns mistakes into progress
Timed like the real thing
Sit each practice test against the clock, flag questions to come back to, and get used to the pace before exam day.
An explanation for every answer
Review mode walks through each question, right or wrong, so every mistake turns into something you understand.
Results by topic
See where you are strong and where you are losing marks, topic by topic, instead of a single score.

How does AI test prep work?
You create a study plan for an exam, such as the SAT or your biology final, and optionally add your own material. CramX generates practice tests for that plan, times them, explains every answer and breaks your results down by topic.
Which exams can I practice for?
There are built-in plans for the SAT, ACT, GRE, GMAT, MCAT and LSAT, and you can create a plan for any course or certification by describing it and adding your study material.
How much does it cost?
Creating a study plan costs 15 points, and new accounts get 50 free points. Premium plans include unlimited test prep without points.
Are these official practice tests?
No. They are AI-generated practice tests modeled on each exam’s content areas and question styles. Use them alongside the official practice material published by the test makers.
Can I review my mistakes?
Yes. After each test you can go through every question with the correct answer and an explanation, and your results show which topics to work on next.
Does it work on my phone?
Yes. Plans, tests and results work in any mobile browser, and your progress is saved to your account.
