My readiness score dropped

If your readiness score is lower than it was yesterday and you did not fail anything, you almost certainly hit decay.

How decay works​

Readiness is a memory model, not a transcript score. After a one-day gap with no roadmap activity, I subtract 3 points per day from your readiness until you study again. The decay reflects realistic forgetting — the longer you go without touching the material, the less ready you actually are for the exam.

The decay is applied automatically and shows up as a downward tick on your readiness gauge.

How to recover the points​

Decay reverses as soon as you study again. The fastest paths back up:

  • Complete today's roadmap task. This is the strongest signal. One on-roadmap session is worth more than several free-play sessions.
  • Work the Error Dashboard. Targeted remediation on weak domains restores domain mastery, which feeds the overall score.
  • Validate a milestone if one is queued. Milestone validation is the single biggest readiness jump in the system.

Free-play practice does not count toward readiness recovery the same way roadmap work does. See Two lanes for why.

Why I am strict about it​

A score that only goes up would lie to you. The pass-guarantee math, the predicted-ready-by date, and your public readiness profile all rest on the assumption that the number reflects what you would score on the exam today. Decay is the mechanism that keeps the number honest.
