The upper volume has some markings in red pen and pencil (see photos). The lower volume does not. There were no cut-off sections in the answer sheets. Please forgive any oversights, as this is a layman's inspection. I would appreciate it if those who understand that this is a used item would purchase it. The name written on the upper volume will be cut out (white-out in the photo).
