Refund policy

Last updated: November 2, 2026

In short: if you buy Pro or the AP Exam Pass and you're not satisfied, email us within 14 days of paying and we'll refund you in full, even if you've used it. Pro renews until you cancel; cancel any time and you keep access to the end of the period you've paid for.

1. Free trial

A new account gets a free week (7 days of full access), starting when it answers its first question. No card is needed, nothing is charged and there is nothing to cancel.

Pro bought at checkout starts with 7 free days if you haven't had a free period with us before (one free period per person across our sites: the free week, a card trial or a Founding month). Your card is taken at checkout but not charged until day 7. Cancel before then from your account and you pay nothing. Otherwise Pro starts straight away, and checkout says so before you pay.

2. 14-day money-back

Not satisfied? Email us within 14 days and we'll refund you in full, whether or not you've used the site. The 14 days start:

• Pro ($49 a year or $8 a month): from your first payment for the plan (the first charge after the free days).
• AP Exam Pass ($29 once): from the day you buy the pass.
• Renewals: if your plan renews and you haven't used it since, email us within 14 days of the renewal payment and we'll refund that payment.

When a refund is issued, the plan or pass it paid for ends automatically and its paid access stops. Your account, your progress and the free parts of the site stay.

3. Renewals and cancelling

• Pro renews automatically, every month or every year (you choose at checkout), until you cancel.
• Cancel any time from your account ("Manage subscription") or by emailing us. Cancelling stops the next renewal: you keep access to the end of the period you've paid for, and nothing more is charged.
• Apart from the money-back above, we don't refund part of a month or year when you cancel.
• Switching between monthly and yearly from your account is worked out pro rata: Stripe adds the difference for the rest of the period to your next bill, or takes it off.
• The AP Exam Pass doesn't renew, so there is nothing to cancel.

4. If something doesn't work

If something you paid for doesn't work as described, tell us. We'll fix it, and if we can't within a reasonable time, we'll refund some or all of what you paid. Charged twice by mistake? We refund the duplicate whenever you notice.

5. How to ask for a refund

Email pbromfield@ibmathrevision.com with:

• the email address of the account, and
• what you bought and roughly when.

No form, no questions you have to answer. The account holder or the person who paid (for example a parent) can ask. We give these a priority response.

6. When the money arrives

Refunds go back to the card or account you paid with, in US dollars, through our payment provider Stripe. There is no fee. After we send a refund, banks usually take 5 to 10 business days to show it.

All our sites share one payment account, so your card statement may show "IBMATHREVISION.COM" as the merchant (for the AP Exam Pass, with "AP MATH" after it).

7. Card disputes

If you don't recognize a charge, please email us before you contact your bank. It's usually the quickest way to sort it out.

8. Your legal rights

This policy is on top of your legal rights. Nothing in it takes away any right you have under the consumer protection laws of the state or country where you live, including your rights if something you paid for is faulty.
