His statistics show the people who had been performing poorly through the entire semester and all of the sudden score high. As someone who consistently scored high in college, making the Deans list, scoring mostly As with a few Bs. If I were presented with the testing materials in advance, I would not pass on the opportunity to see the exam before I took it. I would also not admit to seeing it unless it changed my average as compared to the other exams I had already taken. Scoring 5% higher than average will not raise any red flags. It is the people who score 10%+ higher on a mid-term exam that raises red flags. Also, this guy getting ready to cry about people cheating on his exam is lame. Dude is too lazy to make his own exam and is surprised (and offended) when people got the test questions from the same source as he did. The teachers that lecture on what they think is important, but give the standard test that doesn't cover what they think is important suck as teachers (me speaking as a student). In those classes, you have to ignore everything the teacher says and just read the book if you want to do well. This guy has 20 years of experience of teaching what he wants and presenting his students with standardized exams. I am glad this happened, now he can test on what he teaches as opposed to testing on material that he forgot to cover. It will make him a better teacher and his class a better class to take.
