I remember my experience with an entry level business class - I wasn't sure what I wanted to major in, so I took it to see what I thought. Overall, I thought it was an easy class (and I ended up studying a lot with Ernest Nzigamasabo - great guy!) but I learned enough there to stay away from the business school. I was sick at the start of the quarter and did badly on the first test. I could have dropped the class and gotten either a full refund or 3/4 refund at that point, but I decided to speak to the professor. My concern was whether I was already too far behind to catch up. She told me that if I stick with the class and do well I could still get a good grade. So I stuck with it. I got a perfect score on all of the homework (most people did - it was primarily busywork) and I got the highest score in the class on the remaining tests and also on the final. So imagine my surprise when I got a C in the class! I went to talk to the professor about it, reminded her of our conversation and told her I didn't consider a C to be a "good grade". She said that she was sorry, but that's just how the numbers worked out. If she meant what she had said, I should at least have gotten a B. That inflexibility showed me I had no interest in going down that path.
Having said that, when I was close to graduating with my Comp Sci degree, I had to choose a "focus" and I picked a business application based one which had a couple of business classes. Easy A's. Maybe I should have stuck to business - my GPA probably would have been better!
