Geometry (learning triangles and polygonal stars, mainly on parallelograms)

Function (there is a function in grade two, an inverse proportional function and a quadratic function in grade three, which should be advanced)

Statistics. Probability (this is very simple. 100% will do it as long as you are careful in class)

Solve the equation (I want to learn 2 yuan's 1 degree equation well. Algebra is the foundation).

I wish you good grades!
