Middle School Proficiency Training Textbook Science All Grades Revised Edition This is a problem book for middle school science. I previously purchased it on Mercari and used it, but I am selling it because I no longer need it. There are a few places with writing, but they can all be erased with an eraser. The writing is mostly just ○✕ marks, so it shouldn't affect your use of the problem book. I didn't carry it around much, so it's in relatively good condition. Please see the images for details. I am also selling the 3rd-year edition of the same series, so please take a look if you're interested. If you have any questions, please feel free to ask.
