It will definitely work! Can be used as a preview. In this way, you won't be afraid to keep up with the teacher's rhythm in class! If you have mastered the stepping stone to learning mathematics, it is actually possible not to make up lessons. Make up lessons can be mastered deeper, if you are a diligent child. It is better to do more questions!

If you are not good at math, go to make up lessons quickly. You can't skip class. Otherwise, I won't understand it in the future!
