This is a set of three books: a high school Physics Basics textbook, the Lead α Physics Basics workbook, and its answer key. I didn't see any writing, but there might be some I missed. The textbook has some folds, and the workbook has some scuffs. The name on the answer key has been erased with a permanent marker. The textbook and workbook had name stickers, which have been removed. The QR codes were erased in the photos for the listing, so the ones on the books themselves can be read without issue. These books were used for one year. Please refrain from purchasing if you are concerned about minor details.
