Just to add a little bit to what the others have said (btw, nymcstudent's booklist is money, listen to him).
Rotations are lottery-based, and you can get screwed. I wanted to do all of my rotations in the City, and got them all in the City. Except Medicine, which I plan on going into, was at one of the not-so-good places to do it at. So, I was able to get everything switched around such that my first half of the year I'm at Westchester (doing Medicine at the hospital here... definitely the best place to do it), and the second half in Manhattan. You will find that it is easier to get the Westchester rotations than it is to get the NYC ones because everyone wants to move to the City after spending their first two years in Valhella.
I don't recommend renting a microscope from the school vendors. DONT BE TRICKED INTO RENTING ONE! Seriously, you only need it for three classes in all of your four years in medical school: Histology, Microbiology, and a little bit here and there for Pathology. Most of the time you can get away with borrowing someone else's scope. What I do recommend, however, is waiting till you get on campus and your inbox is flooded with people selling stuff, then buy a microscope off of one of them. You won't need a microscope till a month or so into your first year, so you got plenty of time. Then, you can sell it to wet-behind-the-ears first years after you're done with it.
If you're gonna live in Grasslands II, I got the perfect AC for YOU! Perfect fit for the sleeves. I'll sell it to you for $200, lemme know. Again, don't buy it from the company the school tells you to buy it from. I don't know why some of these administration people are so cruel to you first years making you waste so much money with frivolous "suggestions."
Make sure you subscribe to the scribe service and also buy the old exam books. Best investment you will ever make... EVER!
Finally, tuition's been going up every friggin year. It's ridiculous that the budget for on campus students is in excess of $60,000 this year. My point is, save money wherever you can. Don't buy books you won't end up reading. Don't rent microscopes, cook your own food instead of eating out, common sense stuff.
Anyways, lemme know if you got any more questions. I just finished my second year and am studying for the Step 1 but would be more than happy to help you out if I can, provided you buy my AC from me.
j/k . Don't PM me though, my box is full and I don't wanna clean it out. I'll check this thread every so often.
