MCAT: 34 O (~92nd, ~50th percentiles)
Physics GRE: 930 (94th percentile)
General GRE:
- verbal 560 (~75th %le)
- quantitative 800 (92nd-100th %le)
- writing 5.5 (~86th %le)
I found the GRE verbal and analytical parts to be very easy compared to the corresponding parts on MCAT. My time spent ratio for just these parts is probably 1:50 (GRE:MCAT). Overall, I spent 3-4 weeks on studying for GRE (moderate studying, nothing hardcore) and about 3 months for MCAT (5-8 hours pretty much every day). To me, MCAT was much more stressful than the GRE. Maybe, it's because I wrote the GRE a year after the MCAT...
