Depending on your study purpose, online courses are more suitable for workers with basic experience in the industry. They use their spare time after work or weekends to charge themselves to improve their technical ability.

The cost of self-study is low, you can study according to your own study plan, and the time schedule is relatively free. However, the time period is very long. If there is no foundation, it is difficult to teach yourself, and most of them are not suitable.

For people who change careers with zero foundation, offline face-to-face teaching is more efficient, and they spend the least time learning more knowledge and finding a good job. As for the cost, it is still relatively expensive. If you change careers, I suggest you attend training courses, which can save you time. The process of self-study is very difficult, unlike college students who have enough time for self-study.

Although the training costs money, the learning period is short, and the problems encountered can be solved quickly with the systematic teaching of professional teachers. If we exchange projects and discuss with classmates, the effect will be better.

Snail College, our professional IT training institution, will guarantee employment and minimum starting salary after training. There is a special employment team to provide "2 pairs 1" employment guidance, which is more likely to win than self-study job hunting. You can measure time cost and rate of return.
