A completion percentage tells you how much content you watched. It does not tell you whether you can pass. Our readiness score is built on evidence of what you actually understand.
Weights are renormalized over the signals available for your track, so they always sum to 100%.
Your accuracy on practice questions, weighted the way the real exam weights each domain. This is the core signal: can you answer exam-style questions correctly?
How much of the exam blueprint you've actually practiced. A high score on two domains isn't readiness if you haven't touched the other four.
How even your performance is across domains. One fatal weak spot can fail you even if your average looks fine, so we penalize it.
Whether you've practiced recently. Knowledge fades; recent, active recall is a better readiness signal than something you studied a month ago.
For tracks with labs or missions, whether you've applied the concepts, not just recognized them. Included only where a track has hands-on work.
