Glossary

Knowledge point(知识点)

One teachable idea — the unit of the knowledge tree. Learned once from the companion book, then practiced in each competition's own style.

Knowledge tree(知识体系)

The track's shared table of contents: chapters of knowledge points, in learning order, aligned to the standard books.

Companion text(配套教材)

The book chapter that teaches a knowledge point — e.g. AoPS Prealgebra ch. 7 — read before practicing.

Diagnosis(诊断)

The opening round: one pass over every knowledge point at the hard tier, so all later practice is aimed instead of guessed.

Exam simulation(全真模拟)

The contest's form: the same question mix and the same clock, slightly harder than the contest itself — the score is a true reading.

Full mock(模拟考试)

A full-length, blueprint-weighted paper at the hard tier, sealed until submission.

Daily paper(每日卷)

A half-length blueprint-weighted paper — the plan's everyday workload.

Hard drill(强化训练)

A round aimed at your weakest knowledge points, misses first.

Mistake book(错题本)

Every missed question collects here with its working; answer it correctly twice and it clears itself — once is recognizing, twice is knowing.

Chapter quiz(章测)

The knowledge tree chapter's big quiz — 50 questions mixing every knowledge point in the chapter.

Section quiz(章节测验)

A course section's mixed round: choosing the method is part of the work, as on contest day.

Free diagnosis(免费诊断)

Each learner's one free sitting — the diagnosis on one course, no card needed. Finishing any round uses it.

Pass mark(及格线)

The calibrated cut for a Simulation — the score that would have made the contest's cut.

Focus(专注度)

The share of a round's time actually spent on the question page rather than in other tabs.

Answer sheet(答题卡)

The per-question map of a finished round: green right, amber right-but-shaky, red wrong, gray unanswered.

Stage(阶段)

The knowledge tree's four learning stages — Pre, Intro, Intermediate, Advanced — matching the AoPS book ladder. Stages guide; they never gate.

AoPS (Art of Problem Solving)(AoPS（Art of Problem Solving）)

The standard American competition-math book series; the math knowledge tree maps chapter-for-chapter to it.
