I agree with what's posted above. M2, at least at my school, was way more dense and time consuming than M1. I didn't start U World until dedicated. I used Kaplan Q bank throughout the year, but only the few days before an exam when I felt like I had a gone over the organ system enough that doing questions on it was useful. If you're not using Pathoma yet, I would start that now and listen along with your courses. It actually helps with class exams, not just step 1 prep.
I used FA only very minimally during the year (maybe 1 hour per week), in order to review what we went over in class and to see what topics we didn't cover that might show up on step 1, so that I could make flashcards on that as well. I'm not sure what you're doing during those 2 hours every day, but that seems like maybe it's overboard. I think annotating FA is useless, but I know some people swear by it. I suggest this is the area where you could trim time the most.
I think it's great to supplement studying for your courses with some board prep material, but I'd say don't do so much that it's interfering with your ability to do well in classes. In my mind, prepping as well as you can for class exams = getting the foundation you need to do well on step 1. Not everyone feels that way though.
I'd say I averaged spending about 30 min to an hour extra per day with supplemental step 1 study materials throughout M2, though perhaps less during the first few months.
