Generally speaking, every school will have a placement test when they are in the second year of high school. The content of the exam is that science is Chinese, mathematics, English, physics, chemistry and biology. Liberal arts are Chinese, math, English, politics, history and geography. The score is 750, which is almost the same as the college entrance examination paper. Most schools divide students into one grade, which is simple and convenient and avoids a lot of trouble. But there are unscientific elements, and the pressure of this exam is even greater. Some candidates will be assigned to poor classes because they don't adapt. There are also schools that bring a certain proportion of the grade of Grade One to the grading results, which is more troublesome to operate.
