Ha, I majored in chemistry at a top ten undergrad. Atleast half the people in my classes would manage to acquire "illegal" study material such as old exams that the prof did not provide the class, knowing that the profs mostly recycled old exam questions. Keeping illegal crib sheets under chairs, in laps, etc. was also very common during exams, along with sharing answers with the people around you. I only know of two people who were caught during an exam and they were just given a light scolding. And probably about 90% of the class used old lab reports from former students and molded them into their own. The people who cheated the most rampantly came out top of our class and most of them are going to/in medical school....not saying any of this is okay, but maybe some people on here are just not aware of what their fellow classmates are up to...
