I built a free quiz site with 12,600+ questions based on Josh Starmer's StatQuest playlists - BAM! Quiz
Hey everyone,
I'm a big fan of StatQuest and have been going through both the Statistics Fundamentals and Machine Learning playlists. Great content, but I kept forgetting concepts without actively testing myself.
So I built BAM! Quiz - a free, open-source quiz site based entirely on Josh's two playlists.
What it covers:
- Statistics Fundamentals (20 topics, 5,300+ questions)
- Machine Learning (30 topics, 7,500+ questions)
- 3 difficulty levels per topic: Beginner / Intermediate / Advanced
- Every answer has a full explanation
How the question bank was built: Used the Gemini Flash API to generate questions programmatically, topic by topic, difficulty by difficulty, varying question styles (conceptual, scenario-based, misconception, calculation). Then ran a deduplication pass to remove near-duplicates. The final bank is served as static JSON, so there's no API dependency at runtime — it just loads instantly.
Tech stack: Next.js 14, TypeScript, Tailwind CSS, Vercel

(open source, issue templates set up if you find a dodgy question)
Disclaimer: fan-made, not affiliated with Josh Starmer or StatQuest. All question content is original, inspired by the concepts in his videos.
Would love feedback from this community — you'll spot mistakes faster than anyone. If a question is wrong or misleading, please open a GitHub issue, and I'll fix it.
