There's no reason to sit around and wait on scores before continuing to study, so my plan was always to assume I'd passed and begin studying for the next section, in your case FAR. Taking a couple/few days off can be good (I usually took somewhere between a weekend and a week off between exams), but then start studying for the next exam. If you fail AUD (Exam #1), I'd probably plan to take it next after FAR (Exam #2). So, depending on how quickly you think you can prepare for FAR, either take FAR end of May/start of June, or take it the very beginning of July. Either way, by the time you take FAR, you'll know whether you passed AUD or not, and that way you'll know after you take FAR whether to start re-studying AUD or to start studying your next exam (presuming REG based on your signature) – either one being Exam #3. Then, after you take Exam #3, you'll know whether you passed FAR (Exam #2), and you'll know whether to re-study for FAR or move on to the next exam…and so on till you finish.
There's a decent chance* that you'll pass AUD. But if you don't, the FAR material will only help you with your re-take, and I think the “break” studying for FAR will help you approach the AUD re-take as a fresh study session so that you can study for 75 points, instead of thinking you're just studying for the 2 or 3 that you missed. So, I see no reason not to move on, and a lot of reasons that waiting around is unproductive. Biggest one is that if you pass AUD (again, pretty good chance* of that), then all that time waiting to prepare to re-study will be wasted!
* AUD has a below-50% passing rate. However, there are many people – as you'll see from numerous signatures on here – who took AUD, as well as all the others, multiple times. Statistically, if AUD has – say – a 50% passing rate, and Joe Smith takes AUD 6 times, then he's one person who didn't pass AUD on his first attempt. However, he has 5 fails. So, four people who pass on their first time would average out with Joe Smith to an average 50% passing rate for all (5 total passes, 5 total fails). That would mean that among Joe and these 4 people, 80% passed on their first try, even though AUD had a 50% pass rate. Now, in reality, the people who take 6 tries to pass are not one in 5, and the pass rate is a little lower than 50% which makes the numbers harder to do easy examples, but my point is that the first-time pass rate is higher than the overall pass rate, because every person who has 6 tries to pass has to be balanced out by several who passed on their first try. So, don't see a 43% pass rate or whatever it is currently and think that means as a first-time test taker you have a 43% chance of passing, cause I theorize that first-time taking of a section has a higher pass rate than the overall pass rate. Everyone who takes it twice has a personal average of 50%, so higher than the overall, but everyone who takes it more than twice has a personal average of 33% or less, so lower than the overall, so I think that in general repeat takers lower the average. So, I believe that the odds of a first-time taker passing are greater than the odds of them failing, for all of the exams, not just BEC.
