I erased the check marks (◯✕) written in pencil next to the problem numbers. I erased them cleanly, so I don't think it will bother you.

There are no writings on the solution formulas or diagrams. - Target Grade: Students preparing for middle school entrance exams - Features: Content specifically for advanced school entrance exams - Time Guide: Aim for 15 minutes of study per day Mabuchi Education
