How Per-Subject Purchases Work

If you only need one or two subjects, you can buy access to individual subjects as a one-time payment rather than subscribing to Pro.

Go to the subject page and click “Unlock this subject.” You will be taken to a Stripe checkout. Once purchased, you have permanent access to all content for that subject — MCQs, exam questions, flashcards, revision notes, and cheat sheets.

Per-subject purchases do not include increased AI question limits — those are tied to Pro and Max plans.
