The main contents to be studied in junior middle school mathematics are: the relationship between edges and corners of right triangle, inverse proportional function, quadratic function and circle. It seems that the knowledge content is not much, but it is the focus and difficulty of mathematics in the senior high school entrance examination. First, it is very normal for the inverse proportional function and geometric synthesis to appear in the fill-in-the-blank questions in the senior high school entrance examination. Furthermore, for a circle, it is the most learned geometric figure in plane geometry.

The test sites and questions involved are also the most, and the difficulty of the senior high school entrance examination is not small; Finally, the quadratic function in the form of the final question of the senior high school entrance examination can almost be regarded as a compulsory final question. To sum up, the learning content of senior three is not difficult and plays a decisive role in the senior high school entrance examination.

How should I learn?

Strengthen the foundation: no matter what you study or test, you can't do without basic knowledge. Grasp the basics at the beginning of learning, don't just ask difficulties.

Appropriate expansion: on the premise of mastering the foundation, expand accordingly. For example, inverse proportional function and geometric synthesis can be contacted as soon as possible, and the finale of quadratic function should be trained frequently, so don't miss the opportunity of learning because time is too tight.
