mh1086,
I am using BISK for each section. I use online access, books, and video lectures. I make sure to do every MC question in the text and online. It can get a little redundant, but that's the way I learn best.
I have given myself four weeks for FAR, three weeks for audit, and a week for BEC. I really rushed BEC because the window was extended into March. Some people will probably get mad at me for saying this, but BEC was extremely easy, in my opinion. I received the lowest score on that exam though.
I've been studying REG since the 15th of March and am now into the cram-and-review-mode of my studies. I'd honestly say that you can pass BEC easily with no more than 40 hours of study (I'm gonna get hate mail for this one).
Which study materials are you using?
