How it works

Old exam in. New practice exam out.

Aprovement copies your exam. It takes about one minute to get your first question.

  1. Add your files

    Old exams, slides, notes or a recording of your class.

  2. It studies your exam

    It sees how your exam looks and what kinds of questions it asks.

  3. Take a practice exam

    You get a new exam that looks like the real one. Use a timer if you want.

  4. See what to fix

    Every answer is explained, and shows the page it came from.

Try it with your own old exam

The method

Eighty percent practice. Twenty percent notes.

Reading your notes again feels good, but it does not help much. Answering questions like in a real exam does. So Aprovement is mostly practice.

    Correct. Protons flow back through ATP synthase, and that flow powers it.Lecture 9 · p. 14

How does the practice exam work?

Add old exams and your class files. Aprovement sees how your exam looks and how it is marked. Then it writes a new one from your files and explains every answer.

Can I trust the answers?

Chat answers come from your files and show the page they came from, so you can check. Like any AI, it can be wrong sometimes. That is why the page is one click away.

Does it work for maths and science?

Yes. Take a photo of a problem and see it solved step by step. Formulas look like real maths.

Can I use it on my phone?

Yes. The iPhone app can record lectures, do flashcards and solve photos. It uses the same account as the website, so your files are on both.
