Catalogue

Courses

Filter by department, subject or difficulty. Every course lists its modules, lessons and the assessments you must pass to be certified.

JavaScript is off. Browsing, reading lesson previews and verifying a certificate still work, because each page ships real HTML and the server renders the content. Signing in, enrolling, tracking progress and taking quizzes need JavaScript — the whole app is a set of ES modules talking to the G WORLD API.
