Exhausted Week!!

I find this week to be exhausted because I am determined to pass my tests but I am not able to pass in some of my subjects. Last Monday, I studied my notes very well but I can't explain why I got low in Social Studies. I get disappointed when I received my testpaper because some of it are low and i think that my efforts worth nothing. I told myself that in the next periodic test, I will study very hard already. That's all for this week..
