In fact, whether it is self-study or training, it is just a learning method, and there is no difference. In essence, it depends on whether you are willing to pay time and energy.
At present, IT training institutions mostly focus on offline face-to-face learning, with a strong learning atmosphere and binding force. This is more important for those students with poor self-discipline. Lecturers of good training institutions have generally worked in the front line of enterprises, and will follow up the needs of enterprises to carry out systematic training, cultivate your programming thinking, answer questions and let you take fewer detours.
Another point is that learning is relative and it is impossible to rely entirely on training institutions. In my opinion, learning is a matter for two people. Teachers work hard and students work hard, that's enough! How far an individual can go in his career mainly depends on his professional skills, learning ability and subjective initiative. Training institutions can provide some convenient opportunities to enter enterprises.
