Question on Level 1 CFA Exam Quantitative Section?

I'd like to know, from someone who has taken it, what is the emphasis of the quantitative section of the LEVEL 1 CFA Exam. How many of the statistical equations did you memorize? I understand most of the concepts well, but their are so many equations!! I am specialy having trouble with the probability concept equations. TVM I can do in my sleep, and distributions I get.
