I'd like to know how many problems the students expected to encounter verbatim or near-verbatim on the test. Were they hoping to see a few identical or similar questions? That would seem to be the typical scenario when you're studying off old tests or, for that matter, the homework problem set. If any show up on the test, great. If a lot show up, you're lucky. Or, did they think it likely that the studied material would make up half or more of the actual test?
