FA is indeed just lists and lists of stuff...I found it kind of hard to get around FA while I was still taking classes, just because I was in a different "mode" of studying. In my experience, studying for boards is not at all like studying for classes, and one has to develop different types of study habits/methods for boards. Not sure how your schedule will work out, but if you're 3 months out and still taking classes, don't let the format freak you out. Once you start focusing on boards studying, you get used to FA very quickly and soon figure out how to fit it into your method of study.
I did what the above poster did: I kept my FA open at all times to the system I was studying that day, and flipped back and forth between FA and my references/secondary sources. Took notes from secondary sources into FA. Basically, I was using FA as a sort of check list to make sure that I was covering all of the essentials in my other sources, and if I had extra time that day, I read beyond what was covered in FA. Then I copied notes from UW into FA. Did all subjects in 2 weeks and 2 days, and by the time I was done, the outline/list format of FA provided a good way to review subjects very quickly.
