In fact, the advanced class and the elite class learn similar things and problems, but the latter is better than the former in teaching methods. If the child's academic performance is almost poor, he will choose an advanced class, and if his academic performance is good, he will choose an elite. However, if the academic performance in the elite class is not satisfactory, it will be eliminated to the advanced class; If you do well in the advanced class, you will be promoted to the elite class, or if you study well in the elite class, you will be promoted to the master class. The price is the same, and the master class can only take the elite class.
