Before this: Trees, Ensembles & Gradient Boosting
Forty-five minutes, fifteen questions, no warning about which area. The skill is calibration — giving the two-sentence answer when that is what is wanted and going three levels deeper when the follow-up asks for it.
Built as drills across every earlier track, so gaps surface while there is still time to close them.
Fifty questions drawn from every track, timed, with a follow-up whenever your answer is thin. Scored on calibration as well as correctness.
Worth 500 XP.
