Every training institution has its advantages and disadvantages, and everyone's education method is different.

There are too many requirements online. I suggest you go to that institution and ask for a free audition (any serious place should be allowed), sum up your feelings after class, or communicate with your classmates.

After all, a training is not only the quality of teachers, but also factors such as class size, learning environment and class placement. At the same time, you should ask a teacher if you can change teachers.

What suits you is the best.
