How can we help?
Questions about your account, a lab session, billing, or a retake extension all go to one inbox, read by a person.
Email support
We usually reply within 2 business days.
A lab or exam didn't work
Tell us so we can find your session quickly:
- Your username
- The lab, lesson, or exam name
- Roughly when it happened (and your time zone)
- A screenshot of any error
Plans, payments & cancelling
Payments are processed by Stripe; we never see your card details. Include your username and the email on your account.
Comparing plans? See Pricing.
Didn't pass the real exam?
If you were on a paid plan, email us within 30 days of your exam with your score report, and we'll add 30 days of access free so you can prepare for the retake.
