Terrified

I am scared out of my mind.  The test is here. I'm not performing well on my practice questions.  It seems that everyone else can rattle off more elements than I.  I have never been this scared about a test in my life.  

Dear Lord, please be with me. Please help me think through things clearly and correctly.  If it is your will that I not pass, please help me deal with that in a mature and positive manner.  Regardless, I know I can't do this without you, so please, just be there.
