Signing up takes a minute

No email address, no card, nothing to confirm.

  • No email address. No inbox to check, no confirmation link.

  • Three things to type. A username, your full name and a password.

  • Under a minute. Signed in the moment the form is accepted.

  • Free, with no card. Nothing to pay and no trial that expires.

And then it keeps your work

  • It remembers where you stopped
  • Your marks are kept
  • A drive for your own files
  • Wrong answers come back
  • Streak, XP and a leaderboard place
  • Notes and bookmarks that stay put
  • 20 badges and a certificate
  • The same place on every device

The course itself is open without an account. An ID is what saves what you did in it.
