Everyone has his own learning method. I suggest you try to listen to the audition class before you sign up for class. I signed up for Gao Tu's math class, and my teacher is Zhou Shuai. I have studied for two semesters. Now there are 20 out of 40 students in my class and 55 students in my class. Ha, ha, ha, I still can't catch up with Xueba, but my subject has made great progress. In the past, the total mathematics was divided, but now the interest in mathematics has increased greatly. I'm glad you can adopt my answer. You can keep asking questions. Thank you.
