Not a practice test, and there's no score. It's a map of where your content stands, built to answer one question: of everything you could study, what should you study first?
For each concept you'll do two things — rate your confidence, then answer a question on it. Comparing the two is the point. It finds the topics you think you know but don't, which are the ones you'd never have chosen to study.
What you could do right now, not after a review. An inflated rating doesn't cost you anything here. It costs you study time later.
It doesn't count against you, and it beats a lucky guess — a guess that lands tells us you're fine when you aren't.
Use the same address for both sections so your report covers everything.
An approximate date is fine. It sets the length of your schedule.
Quick skips the questions on anything you rate 1 — you already know those are gaps. Comprehensive answers everything, which also finds concepts you're underrating. Either way you rate every concept.
You can close this and come back — your progress is saved on this device.

Part A — How confident are you?
Part B — Answer the question
There's no going back — that's deliberate. Revising an earlier rating after seeing a question would undo the measurement.
