@Katie I think 7 weeks for AUD will be sufficient. I took the exams in the old(er) format (took AUD in Q3 2015), but – at least at that time – the material was 6 chapters worth (I used Becker). I studied from the beginning of May until the end of June (and took the exam one of the first days in July). So, that came out to more like 8 weeks, but I think 7 still would've been sufficient. I passed with a 77 on my first attempt.
I don't quite know how to verify if 15-20 hours a week is what's necessary, but I probably put in about that much time per week. I think you should just make sure that you have a game plan and an organized calendar. Let's say you divide up the material and “to-do”s over 7 weeks. For – say – week 3, let's say you get to Saturday, and you still have 40% of your “to-do”s to cover. You'll just have to sacrifice other things that Saturday and do anything in your power to make sure you finish your materials for that particular week. Does that make sense? Regardless of how many (or how few) hours it takes, just give yourself goals and milestones to reach at the end of each week, and treat each week as a new challenge. For me, that made it more entertaining to study.
Based on your FAR score of 90, it seems like you definitely know what you're doing for these exams. Best of luck to you on AUD!
I hope this has been helpful!
