ahh, their math teach is like some profs I had. There was a question on both midterms with material not covered, so I questioned my prof that it isn't very fair and his words, I shit you not were "Why would I give you a test I knew you could get 100% on? There wouldn't be much point to testing you then" Basically their justification is that you are just combining knowledge from the class and other classes you've hopefully taken.
