Textbooks? (for a Freshman Engineer)

<p>Is it too early to start buying textbooks? I was hoping I could nab some cheap used ones before everyone starts buying them. What textbooks would I need for these classes if it is ok to start getting them:
Math 1910
Chem 2090
ENGRI 1110 (nanotechnology)</p>

<p>The new booklist would not be updated until August 8th. I would wait until the list comes out because buying the older edition is just going to hurt you a little bit. Also, check on Kraftees as well as online resources :)</p>
