FAQ
Will I master the material after one stage?▼
Each stage has small steps with a clear goal and quick check. Pass the unit exam after all steps to claim rewards and ensure mastery.
What if I'm stuck on a step?▼
Use the stage AI mentor or L1/L2/L3 hints first. Still stuck? Use "Ask in community" on the stage page.
How are coding steps graded?▼
Code runs in a Python sandbox. Run tests, pass all cases, then complete the quick check and submit.
Can I skip the unit exam?▼
Not by default—you must pass to complete the stage. Dev/staging admins can enable skip in the admin console.
Where do unit exam questions come from?▼
Hybrid by default: mostly fixed review bank (step checks + admin items), with some AI-generated questions.
How are AI mentor, community, and support different?▼
AI mentor: instant Q&A and guidance. Community: discuss and showcase. Support tickets: account, billing, and bugs.
- Wrong quick-check answers show explanations—you must pass to continue
- Code steps with tests must pass the sandbox before submit
- Unit exams cover stage goals—pass to confirm completion and claim rewards
