How to use these
Ten encounter decks — one per math topic. Each pairs a Paper 1 (no-calc, exact form) question with a Paper 2 (GDC-active) question, modelled on 2022-2023 AA HL May papers. Take them after the corresponding chapter quizzes.
What you get per encounter
Question setup → guided per-mark solve → topic-specific traps slide → wrap. Every explanation uses the Per-mark scheme [n]: format so you see which line earns which IB mark.
Recommended pacing
ONE encounter per study session. 22 minutes each. Don't rush — the trap-spotting slide at the end is the highest-leverage 90 seconds in this topic.
Why these patterns
Each chosen question represents a high-frequency archetype in AA HL May 2018-2023. Mastering all 20 patterns covers ~70% of historical mark distribution.
