Placement Assistant

Every attempt records hints used, time taken, confidence and the specific mistakes made — so the system knows the difference between having seen a question and being able to solve it.

A 1/3/7/14/30-day ladder stretched or compressed by how the last review actually went. Full history is kept; nothing is overwritten.

Mastery is a weighted score over independence, consistency, confidence, speed and retention. Every number can be expanded to show exactly why it is what it is.

Company and overall readiness are internal preparation indicators computed from your own tracked data — not a prediction of whether you will clear the interview.
