Practice quizzes that focus on what you got wrong.
Cereby generates quizzes from your notes, then adapts each round to drill the topics you keep missing — no more guessing what to review.



Practice questions that come from your class
The fastest way to find out what you don't know is to be asked. Cereby writes practice quizzes from the material you give it, so the questions use your professor's terms and cover what was actually on the slides, not a generic version of the subject.
Every question comes with an explanation, so a wrong answer teaches you something instead of just costing a point. Ask for an adaptive quiz and Cereby looks at how you did on that subject before: topics you keep missing get more questions, and topics you have down get fewer and harder ones. With no history yet, the first quiz runs from easy to hard to find your level.

A question with its hint and explanation
One question from a quiz built off a cell biology lecture on cellular respiration.
- Question
Where in the cell does the electron transport chain take place?
- Options
A. The cytoplasm B. The inner mitochondrial membrane C. The outer mitochondrial membrane D. The nucleus
- Hint
The chain needs a membrane it can pump protons across, and that membrane is folded into cristae.
- Explanation
B. The proteins of the chain sit in the inner membrane and pump protons into the space between the two membranes. ATP synthase uses that gradient to make ATP. Glycolysis is the step that happens in the cytoplasm.
