Scoring

10 open questions. Closed-book — one double-sided A4 handwritten cheatsheet allowed. No calculator. Assume P ≠ NP and NP ≠ EXP. Karp reductions denoted ≤P. Irrelevant information costs points.

Priority 1 — 22.5 pts (50% of exam)

Three archetypes with fixed templates that repeat identically on every exam. Nailing P1 is the pass/fail line.
