I took REG first, followed by AUD, BEC, AUD (second time) then FAR.
If I had to do it all over again, I would have possibly taken AUD first, because that gave me the most trouble. I took REG first because I struggled with taxation in college, but it wound up being my best score, an 85, the same as I had on FAR. I don't think FAR is that difficult at all, especially if you have been working in accounting for a period of time (same logic can be applied to REG if you are doing taxes, which I was doing at the time I took REG). BEC was just random topics together and AUD was like learning something completely new.
