Am I being obsessive or just competitive?

aww bless you i think its wonderful that you want to do well in your GCSE's! i'm not sure that you are being obsessive or competetive about it though, you just want to succeed. and there is nothing wrong with that. however the only way to get the grade you deserve is to talk to a teacher about it (how about your form tutor), if you told someone how you feel they would surely see how determined and motivated you are about it. maybe get your parents to go in and speak to your head teacher about it if you don't feel okay doing that. i hate that they give kids more of a chance than those people willing to learn. its always the same. good luck in your GCSE's!
