Frequently asked questions
Do I need to be a programmer?
No. Weeks 1 and 2 need no code. Week 3 introduces Claude Code, which you drive with plain-language instructions; comfort with a terminal helps but is not required.
Which Claude plan do I need?
A free account is enough for most of weeks 1 and 2. Some features, such as Projects, Artifacts sharing or Claude Code access, depend on your plan; the lessons note when that applies.
How long is each day?
About 15 minutes: a short lesson, a three-question check and one task to try with Claude.
Will the course go out of date?
Features change quickly, so the lessons focus on durable skills (briefing, iteration, verification, workflows) and point you to the official docs for current details.
Is there a certificate?
Yes. Complete every lesson and pass the final assessment with 70% or more to claim a verifiable certificate.
