As the saying goes, one price for one share. Now the competition in children's programming industry is fierce. If an institution has no core competitiveness, there is no way to stock it. Therefore, in order to ensure their core competitiveness, they generally have their own curriculum characteristics and teaching characteristics.

Nowadays, children's programming education has its own professional R&D team to develop courses for children of different ages, and there are teachers in the organization to teach face to face. If you have any problems in the learning process, you can communicate with the teacher so that more teaching assistants can understand the problems.

On the other hand, on the one hand, the quality of online free courses cannot be guaranteed; On the other hand, if there is something you don't understand, and no one explains it in detail, learning will get stuck in this step and can't be effectively improved.
