The average grade on the first exam was 8 points out of 100 and caused more students to drop the class. This new professor was dumbfounded and perhaps in fear of his job after that test. Fortunately the text book mix up was discovered in discussing the reason for everyone failing that test and the professor did indeed throw out that test and gave only open book take home tests after that point.

Interestingly, I was the only student who scored 100 on the final exam because I was the only person to answer a 1 point question asking who three people were. The three names he listed were the textbook author, the Dean of the College of Business and the President of the University!
