One hour with a tutor costs $100.

Every course has the same three tiers — a free audit, a pass for one exam, and a pass for the whole course. The price depends on how long the course is.

Does anything auto-renew?

No. Every pass is a one-time payment, and we do not keep a card on file for renewals.

What happens when my pass expires?

Your mastery data and mock history stay in your account. You can read them and re-buy a pass any time; practice simply pauses.

Do I need a pass to buy add-ons?

No. Mock marking and the crammer pass can each be bought on their own.

Is this the real mark scheme?

Grading is calibrated against published exam-board mark schemes/scoring guidelines. Redpen is independent and not affiliated with any exam board.

Is there a school price?

Yes — departments are priced per cohort with teacher accounts and class analytics included. Talk to us for a quote.

Never auto-renews

One payment. No stored card, no surprise charge the month after your exam.

Syllabus-guaranteed

Calibrated to the current specification and its published mark schemes/scoring guidelines.

Second course, 40% off

One rule that works however many courses you take, instead of a bundle for every pair.
