Physics and mathematics are the most difficult things in senior one. Senior one is the foundation. If you learn math functions well in senior one, you will basically learn math well in senior high school. The difficulty of physics in the first grade mainly lies in mechanics, which can be said to be the cornerstone of physics in senior high school. I made up lessons in Gaoding Education and took a math class from Wang Liang, a teacher in No.1 Middle School. As an alumnus, you can find out for yourself and find a suitable teacher.
