hey
i just studied for the mcat while hanging out in india. brought books over with me from the US. tried to supplement what I brought and basically concluded stuff online just didn't compare to what i had with me (berkeley review, examcrackers). you can get access to kaplan's mcat qbank for like $140 (insane!) if you just want questions. and of course, aamc's free online tests are available too. but if you're anywhere that can recieve reliable ground shipping, i'd go with ordering kaplan or princeton review stuff from amazon (or exam crackers)...
this all being said, i dunno how extensive of materials you're looking for...if you just want outlines and stuff, you'll find lots online...
