The entrance exams are different from one another in different regions.

Affect the solid ball performance, there are three factors, solid ball shot initial velocity, shot angle and shot height, in which shot the initial velocity is the most important factor. The initial speed of the solid ball shot is mainly determined by the distance and time of the last hard throwing ball. The greater the force distance, the longer the time
