Any suggestions on the prep book ?
There's no single book that'll prepare you for Math and Bio synchronously. :) Anyway,
I think it's kinda late to start cramming now but some light review might do you good. So for math, get the Barron's to go through the formulas and theory and practice with Princeton Review. Concerning biology, there's not much you can do now, unless you have a sound foundation of the covered material. Whatever the case, Princeton Review's book is awesome to grab some fast facts.</p>
