My daughter uses this to learn junior high school mathematics accurately, which is not bad. In fact, junior high school mathematics has two key points, one is the understanding of concepts, and the other is the application of formulas. As long as you master these two points, your math scores will naturally not be bad. My daughter's formula application ability is not good, so she can only do more related questions. Through the evaluation report of the accurate evaluation system, she can see the thinking of solving problems and then do the wrong questions. She has done many related questions, so she is naturally not afraid of the exam. Now she ranks in the top five in the single subject class, so she will work harder in the summer vacation and take the exam first, haha ~
