Questions

How can I cancel?

Any time, from your account: “Manage subscription” lets you stop it renewing at the end of the period you’ve paid for.

What do I get for free?

Every chapter, and any 3 practice sets of your choosing with a free account. Free sets stay yours.

Can my students get a discount?

Teachers get heavily discounted access for a whole class, half the Annual price a seat: request it here. We can’t set this up for individual students, so if you’re a student, ask your teacher.

What if I don’t like it?

Email within 14 days of buying Annual or Lifetime, or during the month you’re in for Monthly, and we’ll refund you in full, for any reason. One refund per person; a refund ends the Premium it paid for. See the Terms.

Can I invite friends?

Yes. Your account has an invite link. Friends who use it get 20% off their first payment, and once 5 of them have bought Premium (and kept it past the refund window), you get 20% off your next payment. One reward per account; Lifetime owners have nothing left to discount. An invite discount takes the place of a promotion code.

Where do I use a discount code?

Press any Upgrade button. Checkout has a field for a promotion code.
