Natural Science angst

I'm really worried now. I failed the my second long exam in nat sci. I failed the first one too. I'm gonna be in trouble. I don't wanna take the subject again. I wish and hope above all hopes that I pass. God, please let me pass. I really don't wanna do a repeat. crap. Now i have to work extra hard in physics to get the highest grade ever so I can pass. God, please let me pass. please.
