physics = hell !!!!

Physics paper the day after tomorrow and i still ain't confident. I don't know why but i can't seem to learn anything ! I have forgotten things i knew earlier and half of the things i didn't know goes over my head. Only GOD can save me now !!!! I haven't got enough practice and i certainly can't achieve that in one day. Hope some miracle happens and we are given an easy paper ...... AMEN !!!!
