Step 2: 274
Step 1: 254
I think my approach to studying during M3 year helped. I outlined 1-2 books for each shelf and supplemented the outlines with new info from Uworld. During my study period, I used First Aid for Step 2 and Uworld, but FA was not as comprehensive as my shelf resources had been. There was no time to reread those books (although I did redo Petastana - it was quick and worth it), but with my outlines I could quickly restudy all the material that I'd deemed high yield before. So I'd definitely recommend outlining/taking notes throughout M3 year. It was a pain and took a lot of time, but it paid off.
Also, don't be afraid to give yourself more time than the standard 2-4 weeks. I spent 5 weeks for Step 2 (while doing a very light elective) and 6 weeks for Step 1. For me, more time meant I could go slow and process everything fully. Maybe I would have had the same scores with less time, but I doubt it.
