This is a set of the 2025 edition physics study guide, including the basics and a separate explanatory booklet. It was distributed as a textbook for compulsory high school subjects, so it was only used a few times for regular test preparation. There are minor scratches on the surface, and some writing inside, but the writing has been erased and is almost unnoticeable. The name was written on the back cover, so it has been erased with alcohol and covered with a white sticker.
