Free to start. One simple upgrade.

Every past paper and every interactive is free, for as long as you like — and so is the first 60% of every course, with no account needed. A free account adds a few AI markings and Ask AI questions every week. A paid plan opens more of every course and makes the AI tutor and AI marking work without setting anything up.

Plans and billing.

What does the Free plan include?
Every question bank and interactive, the first 60% of the lessons in every course, notebooks and your progress, and 7 AI markings and 3 Ask AI questions a week. A guest gets the same without an account.
What does Pro add?
Every lesson in every course, and the AI tutor and AI marking included — no key to set up. See pricing.
Is there a yearly plan or a student discount?
The plans, their prices and how each is billed are all on the pricing page. There is no student discount.
Can I cancel?
Yes, at any time, from Settings → Subscription & billing. You keep everything on the Free plan.
Is the AI free?
A little of it. A free account gets 7 AI markings and 3 Ask AI questions a week; they don’t carry over, and the count starts again every Monday. A plan that includes AI gives much more. Guests need to sign in first.
Can the AI be wrong?
Yes. Treat it as a tutor, not an examiner. The solution and mark scheme are always on the question so you can check.

Start free. Upgrade only if you want to.

All the practice and most of every course cost nothing.
