I wrote to you, and I'm glad you believe me.

I know you have some difficulties in learning English. I can't keep up with the class because I can't adapt to what the new teacher teaches. Don't worry. I think my following suggestions will help you. First of all, you'd better listen to the teacher carefully and practice more in class. You can ask your math teacher to explain what you don't understand after class. Secondly, self-confidence is very important. You should be confident and believe in yourself. I think you can do it. Finally, you can communicate with your classmates and get some advice on learning mathematics. I think in the near future, you will get used to it and do well. Nothing is difficult if you put your heart into it. I hope you will make progress soon.
