Of course, I am a sophomore in math. I changed my math teacher in grade three. He has many plans and methods, so his grades have gone up. I suggest you or find a teacher to summarize several major knowledge points of junior high school mathematics and break through them one by one.

That year, I got a score of 6 1 1 in No.3 Middle School, and my math was probably less than 1 10, so I went to a key class.
