Follow closely in class.
Review after class
Mathematics is a bit difficult for some people, so if you have any questions in class, you must ask the teacher clearly. Don't let her go after class. If you pay the tuition, then some things are her obligations and your rights. There is nothing to be ashamed of. Learning is never shameful. Don't be afraid to ask the teacher questions.
Finally, you must finish your homework carefully. I hope you get good grades in math.
