How do I reset my progress for a course?

Currently, you cannot reset progress for an entire course. However, you can revisit any completed lesson and watch the video or retake the coding challenge as many times as you like.

Can I download videos for offline viewing?

Offline viewing is currently only available for Pro subscribers on our mobile app.

How are coding challenges graded?

When you submit a challenge, your code runs against a set of hidden test cases on our secure servers. You must pass all test cases to earn XP and complete the lesson.

How do I upgrade to Pro?

You can upgrade to Pro by visiting the Pricing page or clicking the Upgrade button in your Account settings.
