I'm not good enough

I didn't do well in my exam. I think I'm gonna fail my addmath paper again. I don't know why I can't score that paper. besides, biology's the hardest. I answered the paper like I didn't learn biology at all. pfftt -.- chapter 6, nutrition's the longest chapter. I can't finished to read them all that night. pasrah jelah :( I asked  my neighbour isn't biology paper very tough. she said sometimes. well, I know she loves biology. good for her lah :D bery bery stressful. all the form4 subjects kinda tough.
