It should be the type of certificate. College students are the certificates of the Ministry of Education, and after graduation, they are the certificates of the Ministry of Labor. So, both are useful. During school, you can take more certificates from the Ministry of Education, so that you can find a job after graduation. Basically, I don't take the certificate of the Ministry of Education. Take more exams for the certificate of the Ministry of Labor, and you can get a raise to evaluate your professional title!
