How to p organic chemistry III lecture course?

I have a 58% in the cl right now (total), and need a 73% to p. I got a 48% on my first midterm, with average of 50% on my quizzes, 100% on homework and projects. That leaves me WITH HAVING TO GET AN 80% on the last midterm and ACS final as well. I have 5 days to study, of course I will, but any extra advice to p/study techniques?
