A textbook for high school entrance exam preparation, covering key points and strategies. I purchased this last year to help my child prepare for their high school entrance exams. As shown in the image, I found a red line drawn on page 40 of the English section. I've blacked out the name on the English explanation page. When I asked my child, they said they left it at home and hardly used it, haha. I've flipped through it, and I don't think there are any other markings, but I apologize if I missed anything. Please understand this before purchasing. Also,
