Last-minute exam triage: map the official scope to homework patterns before agreeing to 'do all practice problems'

When a student under ~24h to an algorithms exam proposes grinding every lab and every textbook exercise, check the official scope statement first. Here it said 'material featured in Homeworks 5-9'. Skimming the section headings of the student's own homework source files (grep '^=' on the .typ files) collapsed 10 problems into 6 patterns (state-augmented graph + Dijkstra, DFA product graph, Bellman-Ford negative cycle, DAG DP in topo order, suffix/2-sequence/interval DP, D&C with linear-time selection) in two tool calls. Recommending 'redo those from memory, then targeted labs only for missed patterns' is a far better ROI than random coverage. Also check the homework files for LLM-drafted notes: if solutions were AI-drafted, redoing them is real practice, not review.
