I think 10 weeks is the perfect amount of time if you are only studying, but you have to stay on top of it. I was able to do it in 12 weeks working full time. I really recommend doing all practice exams, and spend a decent amount of time of Gov't and NFP accounting. I broke up my sections when I studied as you know each test is VERY different, but I made sure I knew the following topics really really really well: Gov't, NFP, Cash Flows, New Revenue Recognition, Pensions, Leases, Bonds, Debt/Equity Method, Stock JE's (treasury stock – par value vs cost method), Anti/Diluted EPS, Acquisitions/Consolidations, Nonmonetary Exchanges (Boot/No Boot), OCBOA terminology/differences, Capitalized/Expensed Costs – pay close attention/understand internally developed software costs etc, Inventory (LIFO/FIFO if inventory prices are rising the effects on both methods..etc they love those questions), Foreign Transaction/Translation, Depreciation methods, etc.. If you know the big topics well enough/can do the SIMs on these you will be fine, they can get very specific on the exams depending on the exam you get..and if you get those questions right awesome if not it won't make you fail.. I was surprised on how much Gov't and NFP was on my exam and I actually have zero Gov't accounting experience/nor do I like it very much lol Best part about FAR is if you know JE's you can usually figure out majority of sims but I recommend doing all the SIMs especially for Gov't and NFP..the SIMs from Becker taught me more than the MC with the very tough sections I struggled with.. I used Becker to pass in Sept of 2019 with an 83 – and I think the best score I got on a Becker practice exam was a 73. ALSO – make sure you do the AICPA practice exam..it is super helpful to see the types of questions they previously asked..you will notice you get SIMs that have a TON of attachments and it is super annoying lol make sure you plan how to go through all the attached documents to the problems etc.
My best piece of advice after going through all of this is just don't give up on the actual exam/get frustrated while you are taking it..Every single exam I wanted to walk out of and every single time I called my husband/mom afterwards and let them know I would be retaking the exam and I for sure failed. I passed all four on the first try! I realized after I passed BEC with a 78 and I didn't do an entire essay that you just have no idea how to gauge how you are doing.. just give every question your best shot and keep trying on the entire exam! If you do the reps and put it in the time you will pass!
