Currently in Vietnam there is no specific research on whether online learning is really effective. However, according to my personal feeling, there are some websites that do very well, but there are also many poor quality courses that allow instructors to post videos without quality inspection. The problems of Vietnam and the world are completely different. When policies and thinking about how to do education are different. Especially when we develop education without a clear direction!
With traditional studies, those of you who are trained at a prestigious university specializing in import and export can say that your knowledge is quite good. But for those who work in the wrong field, for those who have not been trained through school, it is difficult to start. Currently, there are many teaching centers, but finding a center that is suitable and of real quality for you is difficult.
