There are many criteria and factors for selection, and these important factors should be understood:
First look at the course content. This is the first standard. What did the teacher say? Is this what he needs? However, some teachers copy a little here and a little there. Such a teacher is not worth learning, because he has no core of his own and will always be an imitator. A good teacher's curriculum is self-contained.
Second, see the teacher. Now some teachers' honors are self-styled, and many academic qualifications are boasted. Don't care too much about this. Look at his lecture pictures. Teachers can write articles and blogs. If a teacher has no books, no articles and no related videos, he is a shallow teacher at first glance, and you will know the pattern and realm of this person by looking at the teacher's blog. Age is not a problem, but speaking style is the most important.
Third, look at the company's brand, whether the company has its own characteristics in this industry, high price is not necessarily good, but look at the founder of this brand, his company's products, their company's services and so on.
