Start the testHow it works
- Entry test. 12 questions that adjust as you go: right answers bring harder questions, misses bring easier ones. No answers shown yet.
- Lessons. Short ones, with the spots where you lost points marked.
- Exit test. The same 12 questions again, then up to 6 new ones that keep adjusting. You get a grade going in and coming out, on the same scale, with every answer explained.
Your score is my estimate of how much of the track you know, out of 100: 90 and up is an A, under 60 is an F. The hardest questions are ones I've watched seasoned pros get wrong. Your answers stay in your browser; nothing is sent anywhere.
