Personally, I don't think there is much difference between starting all skills from scratch and introductory education. As long as what your teacher teaches is correct, you have a correct attitude and are really learning, you will certainly make progress. Many people talk about the level of new education teachers. I want to ask whether the level of painting is good or not is not a subjective aesthetic issue. This kind of thing, which is greatly influenced by subjective factors, is not suitable as an absolutely unified measure.
When I was a child, I worked in new education. He said that the teachers in their institution are very careful in preparing lessons and teaching students (he is my good friend since childhood, so there is really no need to lie to me), and my friend is also a trained person, and his professional skills are trustworthy. I believe this institution can still be trusted with such teachers. Especially now, it's hard to say whether anyone will bring rhythm to the one-sided comments on the Internet. After all, the internet world is quite chaotic. Anyway, if it were me, I wouldn't easily deny an institution because of poor online evaluation. What you see and hear is false, not to mention being reported by others. In any case, before you come to a conclusion, try to audition at least once.
