For those who make comparisons to undergrad, well... it is totally dependent on what you did in undergrad. If you were a bio major and did some random other stuff then yeah, med school is gonna be a lot different. You're prob gonna be working harder and longer. Personally I find med school so much easier then what I did in undergrad, both conceptually and in terms of volume. Maybe its just me... or maybe it could be that everyone in med school loves to brag about how much stuff they have to learn. Who knows. All I know is that I am doing well and I have plenty of time to drink beer, read other stuff than med school BS, paint/draw, etc. Med school isn't as hard as everyone makes it out to be. Unless you are a total goofball and don't stay on top of things in a reasonable manner, then you will do fine.
