I gave away my phys and chem textbooks years ago, so I just used whatever I could dumpster-dive or borrow from friends. I was teaching an MCAT course, so I had to go into things in more detail than most people would need to.
I used Tipler for physics because my boyfriend had it and it is a good book; I had a dumpster-dived chem text that was fairly crappy. Often I looked up stuff on the web.
I used Atkins for physical chemistry, because I could borrow it from a friend; that was plenty of detail for the thermo stuff.
I highly recommend Campbell and Reece for all bio and physio topics; their CD-ROM is fantastic for activities to help learn concepts.
