The comprehensive Final

Hello, I have taken the three tests required for this business credit hour. I passed them all but I have noticed that my grade for one of them is a C. I have a comprehensive final today and I want to pass. I have taken this business course over a period of time and now I need to know information about 21 chapters in one morning. Thinking positive would be really handy right now. I think i can... I think i can... Well wish me luck!!
