All four sections must be passed. No averaging. Each is an independent gate.

Study Order Formula

priority(n) = Σk dep(n,k) · wk

Study foundations first. Dependencies determine optimal order.

EXPERIMENTAL — 学習パイプライン

6段階の適応型学習パイプラインDiagnose. Execute. Gate. Loop.

Every study cycle is a pipeline with structured stages. No stage can be skipped. The Review Gate enforces readiness before advancing.

score(t+1) = score(t) + α · (practice_score − score(t))

Score converges toward practice performance. α prevents overreaction to single sessions.

“One loop corrects errors. The other corrects strategy. Both must converge.”

合格ゲート

受験前の8つのチェックPass Every Check, Or Loop Back.

Before scheduling the real exam, every dimension must clear the threshold. The worst score decides. No averaging. No exceptions.

Readiness Gate — Worst-Case Design
Ready(t) = mini scorei(t) ≥ 75  ∧  σ ≤ 5  ∧  coverage ≥ 95%

Uses min_i, not average. One weak section blocks the entire attempt.
