Terms of purchase

What you’re buying

One payment of $97 gives you a personal license to use every lesson in the Online Library and the Desmos practice simulator while signed in to your Deep Test Prep account. It is a one-time purchase, not a subscription. Lessons may be revised, added, or retired over time as the SAT and the library change.

All sales are final

Refunds are not offered. Fifteen lessons are free for everyone, with no account needed, so you can see exactly how the library teaches before you buy. The refund policy explains why. If a payment is reversed through a bank dispute or chargeback, access to the paid lessons ends for that account.

Your account

Each account is for one person. Please don’t share your sign-in, resell access, or copy lessons to share or publish elsewhere. Accounts that do may be closed without a refund.

Payments are processed by Stripe. Deep Test Prep never sees or stores your card number.

What the library can and can’t promise

The lessons are built to help you prepare well, but no course can guarantee a particular SAT score. The SAT is a trademark of the College Board, which is not affiliated with Deep Test Prep and does not endorse it.

Affiliates

People who share Deep Test Prep through the affiliate program earn a commission on sales they refer. Using an affiliate’s link doesn’t change your price.
