Referring to university and higher education in the world in general and in Vietnam in particular, universities today require students to be highly self-aware and proactive in learning to dominate knowledge and meet the increasing demands of the professions as well as the whole society. Students at People's Public Security University are no exception, and the requirements for students in this particular profession are even higher. To be able to grasp comprehensively and in-depth professional knowledge, they must constantly try and make efforts in learning activities, especially spending a lot of time on self-study and find an appropriate and effective learning method.
