David, does your institution provide any formal training for students on the best practices for taking a college level test? Some students do not know what questions to even ask with respect on how best to prepare. Test taking is as much a learned process as is any subject matter and the more your students know about the mechanics of test taking the better overall they will do. This has nothing to do with teaching to a test, rather the techniques they need to know to be good test takers.
