Frequently asked questions
Do I need an account to take the quizzes?
No — every quiz runs instantly in your browser. Nothing is uploaded and no personal information is collected.
How do the difficulty levels work?
Beginner draws from the elements most classes actually meet; intermediate covers elements 1–56; advanced uses all 118 (or the hardest curated questions for trends and compounds).
Are the questions the same every time?
No — questions and answer positions are shuffled each round, so replaying tests real recall instead of position memory.
