Frequently asked questions
Do I need an account to learn?
No. Every published lesson, note, topic page and subject tool is open to everyone. You can try practice questions without signing up too.
What happens to my work when I sign in?
Learning you do while signed in is saved to your account. Work from before you signed in stays separate unless you choose to import it; anything you cleared stays cleared. You can pause or stop saving at any time, and your preferences stay with you.
Do I have to agree to marketing email?
No. You'll need to accept the Terms and Privacy Notice to create an account, but marketing email is a separate, optional choice. Leave that box unticked and you still get the same free account.
Can I buy Premium now?
Not yet. Premium isn't on sale, and there's no sign-up for it. The extras marked Planned are the only ones planned so far. We'll describe each as available only after it's released.
