stupid chemitry!

It's been my worst exam for this term. All formules were ok before the exam but during the exam?? I chose the wrong choices almost 10 times! I am not sure right now, what wrong was?

The other important exam is physic. Tomorrow is my last day to be ready it. There are a lot of formules that are waiting me! I coudn't guess how I can memorize all of them just in a day?

Anyway, tomorrow is my-birtday also. It will be awful tomorrow since I have to work exam! My birtday gift are physic exam and its formules!
