Messed up by Fisika!

These are my friend, as like me, our college fucked up by one subject, and it's Fisika! believe me you don't wanna know what every Monday we have to write -__-

And, after write so many things on those lot of paper, the assistant lecturer just told me to go home, because all I write is wrong. WTF

all i wanna do now is go to sleep, bye
