Your just proved that you're 100% full of shit. Something you don't know is how to spell or write gramatically correct and semantically coherent sentences, which is something useful I learned in college, and do in my job every day. And I just enjoyed the satisfying pleasure of flagging your poorly conceived and written comment dead.
Sure a lot of what I learned is not relevant, but if you asked me to guess which parts would be relevant and which would not I would have guessed wrong.
Agreed, a good guesser would allocate his cheating more accurately by pinpointing the classes that are actually useless, IF his goal was just to learn what is needed.
