It's good to learn computer maintenance. It's good to have two or three months to practice. At that time, you can go out and practice with technicians or engineers, and you can learn a lot. Of course, it is better for teachers to be strict. The strict teacher is more responsible, but after class, I feel very kind. After you graduate, the school will recommend employment, and there are places far and near. Now I am arranged to work in Huaqiang North, Shenzhen, with a high salary.
