I thought I would share my recent experience. I just received a 70 on BEC (after studying for about 4 weeks using Exam Matrix) I started with Yaeger, but I got frustrated because it seemed disorganized and like it was filmed in a poorly lit basement. Anyway, I had taken BEC in March 2011 without studying at all. I made a 70 then too. I guess that proves how random BEC is.
I've now lost my credit for FAR, but have AUD and REG, which expire next May. I'm thinking that I should end this journey now. Not sure I can restudy for FAR since it has changed so much.
