high score

I got a low score in my biology exam. Please pray for me so I can be mentally strong and reappear in my exam with full confidence and achieve a high score.

I need GOD to open my brain and open my mind as i am studying for my math and english accuplacer so that i will have the knowledge and the ability and the discernment to answer all the questions including the difficult questions. I sometimes worry that i might not pass the accuplacer. I need GOD...
