I have been teaching myself financial management knowledge before, but it is only the foundation, and I have been staying at the advanced stage. Then I happened to see them on the Internet. After comprehensive comparison, I bought their advanced courses. When I first started learning, I thought it was like that. Through the teacher's constant guidance, I realized that what I had learned before was too basic to digest with a fierce touch. Later, I won't ask, and I will ask more and more slowly, so I think it is still reliable. You still have to experience it yourself.
