All these books are in good condition and are good prices.
Biology: Biological Sciences (text only) -- Freeman 4th edition -- very good condition with some underlining. (use for both bio 1 and 2)
EES: Living in the Environment -- Miller/Spoolman 16th edition. very good condition with a little underlining and highlighting
PIC: Chemistry in Context -- 6th edition. very good condition. it's technically the international version but it's exactly the same as the american one (yes i've looked) on the inside. the only difference is that this one is paperback and lighter! (use for both PIC 1 and 2)
