I did FARB. FAR first because it's affectionately termed “the beast”. Figured I'd get it out of the way first and know everything else was downhill from there.
AUD fell in place second because I was taking an AUD class and finished the class 2 weeks before taking the exam. As others have said, a lot of overlap between FAR and AUD. So glad I did these 2 in this order.
I wanted to save BEC for last because it's considered the easiest, and I figured even more so for me since I have an MBA and am very confident in the material. I just plotted out my study timeline and I'll get through all of the material and WTB questions in about 2 weeks.
Of course that would leave REG 3rd. Just took it and feel like the exam was on par with FAR, although the time required for preparation was not.
FAR: 4/19/2014 - 85!
AUD: 5/27/2014 - 90!
REG: 7/18/2014 - 81!
BEC: 8/13/2014 - 84!
