The worst from the best

Well, this is my third week at the university and everything is going pretty okay, well, not that much, there's one big problem.  While I make a magnificent job in the lab and have good knowledge in chemistry, I'm failing miserably in calculus, I know I must practice more and more until I have complete domain of the subject, but it's nit being easy for me.
But well, I'm here now, at the top of the mountain, where the liars are thin and it's easy to fell off, there's no turning back from here...
