Hey JRH, I took REG in July '09 and failed with a 74, ouch!
I used Yaeger Home Study! I did excellent on the MCQs, but I was not a good time manager and did not have enough time to do both SIMS, about 1:10.
I also failed AUD with a 70 using the Yaeger Home Study course. The home study course is only 4 DVDs long, so I'm not planning on getting a CRAM course. I'm just going to do the course over again and do every MCQs in the Wiley book that comes with the course.
I did poorly on the SIMS for AUD. I thought I aced the SIMS; I'm doing something wrong; I did not write enough in the written communications.
My advice for AUDIT, is do tons of MCQs and during the exam, take your time doing the MCQs, you have enough time 4 1/2 hours and the SIMS aren't that bad, you just got to know all the material!..
I'm using Yaeger for FAR; finished the course (14DVDs) and am in the process of reviewing all the Modules again. I'm feeling the best about FAR cause I don't want to fail again!
I did pass BEC 77 on the first try using Yaeger Home Study.
Good luck,
