One thing I don't get about university is why they have to have a exam worth 50% of the whole grade....even then they rarely tell you what will specifically be on the test! Take my physics exam as an example, today I go into the test and about 5-10 questions are those that we never studied in class! The prof tells us 5 minutes before the test, "You were allowed a cheat sheet, you know!" Great,  NO ONE ever heard that, however, the prof thought we were all lying...lol One thing I've learned from this is to not trust teachers!!!! jkjk But I was still pretty stressed out at the end...o well life goes on...i guess!!
