How were the quiz questions created?
For each topic (e.g., HTML, CSS), I created a separate NotebookLM with about 200 sources. The keywords were generated using Gemini 3.5 Flash in Thinking Mode, and the questions were formulated through the integration of NotebookLM and a custom Gemini Gem. For all health-related topics, I strictly relied on scientific resources, completely excluding alternative practitioners or unverified claims.

Planned Features
I have planned a lot of updates, including Google Sign-In, a member area (so highscores will be stored in a database rather than local storage), and expanding all quizzes to cover Levels 1 to 12 (3x Beginner, 3x Amateur, 3x Advanced, 3x Expert). Stay tuned!
