Hello,
As far as Nova, and buying stuff...WAIT!!!
You have to order and pay for the white coats ahead of time, most of our class ordered 2-3 sizes larger than normal (I wear a 12 and so I ordered a 20). Most people found this sizing to be good.
The SOSA scrubs were disappointing for most people-they are only sold in same size sets and the pants are tapered (not the most comfortable either). I would wait until you get here, the uniform store that does the coats sells scrubs and has lots of sales right at the beginning of the semester (August), so most of us bought scrubs then (and you can try them on and buy separates so they're much more comfortable).
As far as books, hold off, alot of people sell their books, and we (the future M2s) will probably be having a book sale during the first few weeks of class. I only bought one or two books last semester and one book this semester. THere are PLENTY of books on reserve at the HPD library (that you can check out and look at in the library). Most people did not buy books. AMSA does give away Free Netter's atlases during club week if you sign up with them, they are a pretty active club so it's worth it to join.
Um, other than that, Welch-Allyn will have an equipment sale during orientation or the first week of class, most people got their equipment then, you don't need it before then. They have pretty good deals, you can't find too much better on the internet.
Other than that, just relax, enjoy the rest of your time off, we look forward to meeting your class! See you soon!
