About your programming and software development, I think it should be the other way around. It is obviously more appropriate to report to class. The communication between teachers and classmates is boring compared with self-study. The result is obvious. Self-study is difficult to produce results, and it is also difficult to persist. Of course, self-study is not without, but how many can there be? Let me give you a suggestion. The software pre-job training in Tang Yi, Nanning is good. I have several friends there. Of course, this suggestion is fair ... I feel good.
