So I got this brand new set of bio, chem, and physics review books last summer. They're in pristine condition. Also still have the flashcard set in the wrapping and the High-Yield problem solving guide too, so throwing those in the mix, as well as a lightly used lesson book. Let me know if you're interested in buying, there are 4 solid books + flashcards + lesson guide. Feel free to make me an offer!
