My school decided to invalidate an entire question on the exam, which essentially leaves little of the exam left. My professor essentially revealed to a student that a very similar question would be on the exam, which was based off one of his previous exams on file and there was a model answer for. About 10 students brought in the model answer and copied long portions of it onto the exam. The professor also revealed another topic that would be on the exam, but they decided not to cancel that question because it was such a major topic that everyone knew they had to study.
It works out okay for me, because the question they cancelled I felt I didn't do great on and I didn't spend as much time on it as I should have. What's really messed up is that the professor miswrote the question initially so it was really ambiguous, so classmates wasted 20 minutes answering the wrong question (I just saved it for last). They then had to rewrite their answer without getting more time, and many students wasted a lot of their time prioritizing that question thinking it would get them a lot of points. Now it's entirely eliminated, and some students are furious because the exam has become about luck. Since we are first-year law students and grades are really important, this can affect people chances of getting a job in this economy.
I feel so bad for everyone... but there's nothing else the administration can do. If someone leaks this to some of the major legal news blogs, it can tarnish our school's name. People really dislike the professor to begin with, as he didn't treat us with respect during class (yelling, interrupting, blatant favoritism towards males). He demanded so much of us (it was twice the amount of work as our other classes), and then we ended up getting tested on very little of it. There's also like a Cold War silence between classmates now on Facebook...
