Feeling ready isn't the same as being ready.

Calibrate turns your class notes into practice questions, asks how sure you are before every answer, and shows you exactly where your confidence and your results don't match.

How it works

Three steps to studying with evidence.

  1. Add your notes

    Paste your notes or upload a text-based PDF from class. Calibrate writes practice questions from them.

  2. Say how sure you are

    Rate your confidence before you answer, so your guess is on the record.

  3. See the gap

    Compare what you expected with what you got. Over time, see which study techniques work best for you.
