A situation like yours is not easy to deal with. If you are interested in learning, you can choose to study at night. If you want to engage in this development, it is better to study off-the-job. You get what you want, you lose it. But the computer maintenance training institutions in Shanghai are not very good. I majored in mainboard maintenance at Jiao Tong University, and later went to Hangzhou Huali Computer Maintenance School, where I studied advanced mainboard practical classes. Huali is really good. I studied the advanced practical class of motherboard. There are many mainboards that can be repaired every day. It's really a lot, and it can't be repaired. Gorgeous show seems to have several pits. There are too many motherboards. If you are engaged in the development of computer maintenance, I strongly recommend you to study in Hangzhou Huali Computer Maintenance School.
