Students who have received full-time study are more professional in learning subjects and training methods, while students who have taken the self-taught exam have clear goals and persistent attitudes. If they have a mixed degree, it goes without saying.
As far as personal ability is concerned, most people's ability is directly proportional to their academic qualifications, but there are exceptions.
The causes of ability are related to personal interest and understanding of social work, family environment and social environment, personal ability to accept and understand, and learning methods. I think the process of training and learning is the process of receiving knowledge education and understanding society. In this process, the cognitive influence on society even determines the formation of a person's adaptability to society. A person becomes a member of society. In the process of ability formation, a person's social role orientation is basically certain. Of course, some people have to give up their favorite studies because of their special family background. Sometimes a person gets more things than formal education, such as young Kangxi and some rich children now.
