Good advanced physics/chem textbooks

<p>I just finished Physics C (both) and AP Chem, plus I read Atkins chem book, which I was very happy with. Any thoughts as to books/textbooks to read on my own to learn another level of physics/chem? If you're suggesting anything that'll require math beyond Multi Cal, suggest a good math book to go w/ it plz.
Gracias</p>
