I want to say something you don't like to hear. You don't need to make up for it. The reasons are: first, your child is particularly poor in mathematics. Where can I make up for it? Not to mention that there are many and difficult mathematics in high school. Maybe many people in junior high school don't know how to do it, and it doesn't help to make up lessons. Second, if teachers are invited to make up lessons, the tuition will be very high. If the effect is good, it will be wasted if the effect is not good. In this case, the teacher doesn't want to make it up to you. If you can't get into the undergraduate course, go to a vocational and technical school and choose a good major for employment.
