FAQ

Can I cancel anytime?

Yes. Cancel from your dashboard, no questions asked. You keep access until the end of your current period.

What does the 7-day free trial include?

Full All-Access (or All-Access + Tools) for 7 days. We charge after the trial unless you cancel.

Standard vs Premium — which do I need?

All-Access covers every course. You only need Tools if you take AP CSA (you want the in-browser code runner) or want the AI tutor.

Single Course vs subscription — which is better?

Single course ($30) is cheaper for one subject. All-Access ($60/yr) is cheaper if you study 2+ subjects in a year.

Do you offer school / tutor discounts?

Yes — email us if you want to set up multiple students at once.

What if I bought a single course and want to upgrade?

We credit the unused remainder of your course pass toward an All-Access subscription. Email support.
