Jalbrekt,
The book tip is true...don't buy 'em unless you know you need 'em...with a couple exceptions...1) Buy Netter! and 2) if you are the kind of student who likes a textbook, buy it....the rest will come to you.
Also, try not to get behind.....med school isn't HARD in my opinion...it is draining....mentally and emotionally.....it is about having to study a great deal of material in a short period of time...and then moving on to learn something new....
You will be a better physician and do better on the boards if you study to learn the material, not just try to get good grades on exams....i.e. don't study to just pass tests...study to be a good doctor....
Try to find time during med school for the "little things"...the things that you enjoyed before med school...it will make you happier in the long run.
And on a personal note.... ALWAYS know that there are people who will support you through whatever obstacles come your way, just don't be afraid to ask for help.........and that there is always someone who looks up to you, admires your abilities, and values your friendship........
