"trying to figure out the exam answers in advance using previous exams"
What is wrong with this? My university provides the last six years worth of final exams for every subject, and sometimes the lecturers give you worked solutions for one or two of them. We will often work in groups to come up with solutions so we can practice with them and make sure we've got methods right.
The questions on the exam you take are often completely new (or altered versions of past questions, depending on the lecturer), so it's not cheating at all. But old exams are great practice to make sure you know enough of the formulas and equations to be able to solve the type of questions you will be asked.
