Techniques 1–2, 130 guided problems and the expert replays. No credit card.
All purchases are final — we do not offer refunds on any plan. Weekly, Monthly and 4 Months renew until you cancel; cancelling stops the next charge and keeps access to the end of the period you have paid for. Skills 1–2 are free, so you can try DesPrep properly before you pay. See our Terms of Service.
Questions about billing
What do I get without paying?
The first two official SAT skills, complete — every practice problem, the live Desmos calculator, the step feedback and the expert replays. No credit card, and it does not expire. Two of the Desmos guides also show a preview without an account, and the guide to using Desmos on the digital SAT is free to read in full.
What is the difference between the plans?
Nothing but how you pay. Every plan unlocks all 19 skills and every problem. Weekly is $5.99 a week, Monthly $14.99 a month and 4 Months $39.99 every four months — about $10 a month, and the one that fits a full prep cycle. All three renew until you cancel. Lifetime is $79.99 once, never renews, and includes skills added later.
Can I cancel?
Yes, from your account page, at any time. Access continues to the end of the period you have already paid for, and you are not charged again. This works the same on Weekly, Monthly and 4 Months. Lifetime is a single payment with nothing to cancel.
Do you offer refunds?
No. All purchases are final, on every plan. That is exactly why the first two skills are free and complete with no credit card — try the real thing first, and only pay if it works for you.
Is there a free trial?
No, and deliberately. A trial that quietly turns into a charge is worse than a free tier that does not. The two free skills are the trial, and they stay free.
How do I pay?
Through Stripe, with a card. DesPrep never sees or stores your card details.
