Paperstreak: a free daily paper of real Cambridge past-paper questions

Paperstreak is a free website for Cambridge International O Level and A Level students. Each day it gives you one short paper of real past-paper questions, picked from the chapters you've studied, and every question comes with its official Cambridge mark scheme.

Paperstreak has over 14,900 questions from Cambridge past papers sat between 2016 and 2025. None of them are written by AI.

How the daily paper works

  1. Tick the chapters your class has covered.
  2. Choose how long you've got, from 20 to 90 minutes.
  3. Answer the questions on paper. The formula sheet is one tap away.
  4. Mark each part with the official mark scheme. Anything you lose marks on comes back a couple of days later.

Each paper fits the time you pick, and each question gets the time it would get in the real exam. Old chapters keep coming back, mixed in with what you just learned, so you don't forget them. Every part is tagged with all the chapters it needs, so you only get questions you can do.
