You will end up getting a wide variety of answers to this question.
Someone might put in 200 for FAR and another put in 50. It is not a good metric to base your own prep on (not saying that is why you are asking, just letting you know 🙂 )
That being said, the following was my general experience:
I put my self on a 5 week time frame for each exam. I would apply for the exam and set the test date for five weeks out and then study 3-4 days a week no more than 3 hours a day (I lose focus BAD at around 3 hours). I would throw in an extra day here and there as well. That was my M.O. for the first two exams. My study habits dropped in intensity with the subsequent exams to where I was barely studying for REG at all every day and just drinking a lot instead. My saving grace is that I am a tax accountant and I saved REG for last because I knew I would be sick of studying by that time.
BEC – 75 hours (passed 1st attempt)
FAR – 75 hours (passed 1st attempt)
AUD – 60 hours (failed) 10 hours additional time over two weeks (passed)
REG – 50 hours (passed 1st attempt)
That was my order too. I would wait for one score to come back, to have some time off, before I started studying for my next exam. The exception was my AUD retake. I took that and REG in the same window.
Took me a year exactly, but I was in no rush (already have a job, company paying for review) and wanted to spend a lot of time with my new wife.
