Used set but in good shape. This lot includes 1. Teachers edition book A. 2. Student text. 3. Teachers lab manual and 4. Student lab manual. Lab manual shows the most wear…mostly on cover. First 34 pages ste written in (it’s about 50-60% of the first 34 pages that are written in). Can easily be whited out or erased. All other books don’t have writing. Again, it’s used so maybe an occasional pencil mark or something. Cd is included with teacher book. I have another student text sold separately.
