He will not only fail you if you do,but see that you are thrown out of the college and not allowed to return. Trust me on this,it happened to me in the early 1970's.
So, what's your point? The idea is to get people who already have college degrees to take the class for continuing education. So what if he kicks you out? You arn't going to get your degree. Besides you don't have to be rude or obnoxious to make him look like an idiot. You just have to ask the right questions and follow up with the right informantion.
