Me and a couple of friends from class found this test bank online for the textbook that was currently assigned for class. So we all chipped in a few bucks and bought the test bank. We studied it the couple days before the exam, along with other class notes too. However, someone in the library saw us studying from it and informed the professor about it. He has called each one of us in to question us about it. So far everyone has denied it but today apparantly someone had confessed to the professor we were using the test bank.
So I'm not too sure if this is actually cheating or academic dishonesty. We did not steal the test bank and merely found it online. The exam had about 10-15 multiple choice questions from the test bank.
