When entering the University, it is the dream of many children. In addition to studying at school, self-study for each student is extremely necessary, in order to achieve the expected learning results. However, not everyone can find the most effective self-study method for themselves. In the course of training under the credit system, the amount of time to teach in class for each credit is very short, while the content of knowledge that needs to be conveyed is too much. Therefore, it is inevitable that students must study and prepare lessons before class.Self-study is the process of actively absorbing knowledge and experiences in society and life through personal activities without support from people around. This is a scientific method that helps you resolve the conflict between the infinite amount of knowledge and your limited time.
