Subscribe yearlyBefore you pay
By subscribing you ask for immediate access to the paid content, and you accept that this means you lose the 14-day right to cancel that normally applies to online purchases of digital content.
You can still cancel the subscription itself at any time — it simply stops renewing, and your access runs to the end of the period you have paid for. The refund policy and terms have the full detail, and the free chapters are there for you to try it out before paying anything.
What a subscription unlocks
- Every path and chapter beyond the free Fundamentals
- All full mock exams
- Review, the mistake bank and the notebook
- Offline study on the desktop app, when it lands
- Every platform, one account
- No ads, and no per-chapter purchases
Before you subscribe
No free trial
The first three chapters are free forever. They are the demo — work through them before you pay.
Cancel anytime
From your account page. Access runs to the end of the period you have already paid for, and nothing renews after that.
No refunds
Payments are not refundable — see the refund policy for the full terms.
Nothing is deleted if you stop
Progress, notebook, streaks and mistake bank all stay. Resubscribe and everything is back at once.
