My daughter bought this for her entrance exams, but thankfully she got in through recommendation, so I'm selling it. She was really planning to use it, so the first half of the study guide has some highlighting and notes (photos 4 and 5), but she didn't touch it after that. The dedicated red sheet is also included (photo 3). It was used during travel to and from school and stored at home. Please refrain from purchasing if you are overly concerned about condition. m(_ _)m
