As in the summer after MS1, throughout MS1, or throughout MS1/MS2. Or do you feel that the amount of time you set aside for studying is ample?
In terms of timeline, I would definitely do the same thing again. Starting in January, I read about 5 pages of FA a night and annotated BRS Physio & Kaplan Biochem into FA, so I'd been through everything once leisurely before my 6-week study period.
What I would do differently, I let people talk me out of making flash cards initially (which I had planned to do gradually starting in January as I went through FA). I tried to do it without them, but ultimately, I ended up spending the last 5 weeks making well over a thousand flash cards. Know how you study best and trust your instincts.
