Frequently asked questions
I paid but my exam hasn't unlocked
Some payment methods take a little while to clear, and the exam appears on your dashboard as soon as the money lands. If an hour has passed and it is still missing, email us with the exam name and we will sort it out.
How do I get a refund?
See the Refund Policy for what qualifies, then email us from the address on your account with the exam name and your order details. We process eligible refunds to your original payment method through Stripe.
I found a mistake in a question
Tell us the exam and roughly which question, and what looks wrong. Corrections go to the people who maintain the content, and getting these reports is how we keep it accurate.
How do I change my email or password?
Both live in Settings once you are signed in — you can change your name, email, and password there, and delete your account.
