Let's talk about the advantages and disadvantages of training institutions: the advantages are good hardware facilities, guidance from teachers and good environment. Disadvantages: high tuition, rapid progress, short time, and short time also make you unable to master the technology you have learned at all. I feel that the training class is for people with a little foundation, and zero foundation does not contact training institutions. The school's words are aimed at zero foundation and make up for the lack of training institutions.
