At present, no matter which training mode is on the market, there is a certain time and class schedule, but most types are the same, and there is not much difference. Therefore, when choosing, I suggest that you must choose an institution that suits you and can be recognized by most students in the industry.
It is suggested that you must know more before signing up for the training class, don't listen to hearsay, and you'd better go on a field trip yourself.
As for the arrangement of class time in institutions, it is generally five days a week and two days off, which is basically the same as going to school, except that there are more contents to be learned every day, and everyone needs to spend more time practicing. Classes are held from 9 am to 6 pm every day, and some institutions also have evening self-study.
If you study online, it may be different, because most of them are recorded videos, so the time is relatively free, and everyone can arrange their own time to study.
In short, no matter what mode of study you choose, the basic content of the final study is basically the same. It is important to look at the advanced projects and the post-service situation of teachers.
