These are 2013 versions of the Biology (both parts) and OChem (both parts).
Bio part 1: lots of writing in the passages in the beginning of the book but last few chapters are pretty clean
Bio part 2: no writing or marked answers, new condition
Ochem part 1: writing in all chapters
Ochem part 2: only some notes in the background review sections, no writing in passages, no marked answers
Make a fair offer and we can work out a deal.
