CET-4 and CET-6 are almost compulsory certificates for every college student. Although some students are engaged in jobs unrelated to English after graduation, many enterprises still require students to have CET-4 and CET-6 certificates when recruiting. Because this is a very basic exam, if you don't have this certificate, the enterprise may question your learning attitude and learning ability. With the rapid development of the Internet age, people use electronic products more and more frequently. Now, basically all our work needs computers, so now enterprises require students to have basic computer operation skills when recruiting. At this time, if we have a computer grade certificate, we will get great points in the interview. In the future, whether we are going to be a teacher in an educational institution, taking an examination for teaching or taking a special post, we need a teacher qualification certificate. At this time, if we have this certificate, we can engage in education-related work.
