Frequently Asked Questions

What's the difference between a guest and a registered user?

Guests can browse all lesson content, use the in-lesson code editor, and try a limited version of the playground. Only registered users get the full playground and can save progress, take quizzes, and post in the forum or showcase.

Does switching between Chinese and English affect my progress?

No. Each lesson's content lives in one record with both language fields, so switching the interface language shows the same progress -- nothing resets or gets recalculated.

Can I skip ahead to a later lesson?

Yes. No lesson is locked, so feel free to skim ahead or jump around. What is gated is the quiz: registered users must mark a lesson complete before taking its quiz. Guests can browse any lesson, but can't save progress or take quizzes.

Do I need an account to post in the forum or showcase?

Browsing posts and submissions is open to everyone, but creating a post, comment, or submission requires signing in.
