I used to argue with teachers, star the questions, go up and ask for clarification, write my question on paper so I wouldnt have to talk. In college, professors won't bend to shit.
And yes, I get C's while the rest get whatever. Don't imply that because I get C's everybody gets C's. The tests are poorly written so these gliding numbfucks can understand them because they are the majority and if you talk at all with sense to them they'll either zone out with glassed over eyes, get bored and forget whats going on, or pissed and make an offtopic barely accurate observation.
