Liberal arts students can apply, and so can science students. This major mainly trains criminal investigation, economic crime investigation, public security management, technical appraisal investigation, technical practice talents and teaching and scientific research talents for public security organs, national security organs, procuratorial organs, supervisory organs, customs public security bureau, civil aviation, transportation and railway departments, military security departments, investigation and appraisal departments of courts and judicial administrative organs, and public security management and teaching and scientific research departments.
I suggest you pay more attention to official website. You should have the scores of enrollment in previous years, and pay attention to enrollment publicity. There are specific introductions in it, which can better obtain specific information.
You can also apply for other majors in the Investigation College, such as economic duty crime investigation, public security, criminal science and technology (science only). Western politics is very good, and the judicial expertise center of the investigation college is second to none.
I hope this answer is useful to you. I wish you get into an ideal university and realize your dream.
