It's not really a where question for me. I have a small tablet PC and I just downloaded a notecard app for my android phone, so I can access my electronic "notecards" whereever I am. So far, I've studied on public transportation, in my house, at the school library, and even while waiting at a bar for friends to arrive.
By the way, anyone with an app-friendly phone. Download a notecard app. If I pass med school, I'll have it to thank - I think.
The question is... when will I find time between all of the classes, fluff curricula, and going out to study enough? (M1 here)
