sob sob sob....

Thermodynamics is really getting on my nerves. How am I going to take my test on next wednesday? I've been studying since morning. But of cos I did slack quite a bit in between la.. I'm progressing damn slowly. why? cos I keep reading the same sentence again and again. But I still dun understand. HOW?!?! There are so many equations. I've juz finished reading chapter 2. And in that chapter itself, there are like 75 bloody equations! Am I supposed to remember all of them? I still have 2 more chapters to go. I cant remember so much stuffs lo.. My brain has got limited space. And even after I spend so much time on this chapter alone, I still dun really understand. HOW? It's so depressing... *sob......*
