You can't see bullshit from far, but you certainly can hear a fart!
By farting, I mean blowing your own horn. (pun intended)
Even if you do *twice* as much work on a task/question as others, yet don't brag about it, you are fucked! On the contrary, the more you brag and shout about how much you know or/and have done, the further you will go in class...
