General ACCASBR - Difficulty Level - Would really appreciate feedback on study time

Hi, I am on my final ACCA exam !! I have about 12 weeks until my last one (SBR) that I am hoping to sit in June 2021 The last exam I did was AFM and it took me 3 sittings until I passed. Part of this was not realizing the difficulty level and length of the course. I am not working right now and hoping to manage my time where I can dedicate at least 60% or more of my time to studying over the next 8-10 weeks. I wanted to know about people experience with this exam and if my study time seems realistic? Also I see a higher pass rate for SBR compared to AFM so I was a little more optimistic about being able to pass first time.Is this a realistic assumption as I have read people describing the exam as “extremely difficult”. I would really love to hear your experiences of the exam. Thank you so much in advanced for your feedback I really appreciate it.
