You are probably going to work in clay mostly then, I think. Perhaps stone also. I have tools I can lend you but not leftover clay or stone, since I do not sculpt often and your school will probably want you to purchase whatever the same thing everyone else is using.

The next time you are in the city, text and I can lend you my tools and we can setup a tacklebox for you to organize them in. Mine is not really suited to your needs, and possibly not really easily portable.
