Now that I think about it, here's a clearer explanation of how this was pulled off.
The intrinsic edge I have is that I'm majoring in biochemistry, so pretty much I've mastered all the tested bio / ochem / genchem content even before starting the MCAT reviewing process. I ended up only spending about 2 days going through those three sections from my kaplan textbook, just skimming all the general concepts and refreshing them from my memory.
For physics, same except I read a bit more indepth since though most of the tested phys stuff is elementary, it's still a very broad spectrum of material so I had all but forgotten them since learning them 3 years ago.
I had more or less no time to practice verbal / writing, so I ended up just spending 1 day on them reading up the kaplan strategy guide on HOW to handle them in general, and kind of imagine using those strategies in practice in my head. Other than that I only skimmed a few answered examples to see how they are like.
So in the end, getting a 36 after only 5 days of cramming was a combination of having prior knowledge from my curriculum, and sheer luck, oh and a bit of extra motivation (my friend only crammed MCAT for 3 weeks, also without any practice, back in April, and got a 35 - I'll be sure to brag at him once he gets back from his summer vacation heh).
