# List Exercise History

`GET /teacher-exercise-history`

List distinct library exercises the current teacher already gave.

Draft assignments are excluded — only actually-given work counts.
All Mongo lookups are batched (one query per collection), so the cost
stays flat regardless of assignment count.
