Making up lessons will be useful, but it will cost a lot of money and sometimes waste energy and time. I suggest that if your daughter is poor at math, make it up a little. If it's not that bad, let her teach herself, listen carefully in class, go home and do her homework, and find some PPT online if she doesn't understand the knowledge. It is best not to make up, because if you make up, you must continue to make up, and you can't stop. I've never made up math in my life. I always listen carefully in class and occasionally go online to see what I don't understand. I think math is very interesting.
