Exam Key Success Factor?

Okay,

we have 3 books, power point presentations, 1000 sample questions for practice, old FRM exams, and many many formulas to remember.

What is the key success factor for the exam?

There is 29 days left to take the exam, and I am just really lost on what to focus on! I’ve been already studying a lot, but I am not confident that I remember any of the formulas!

What should I focus on? I still have about 100 pages to read from the last book to complete my chapter understanding…

Also, do they provide any formulas in the exam?
