If you are an English major in a domestic university, it is impossible to skip CET-4 and take CET-8 directly.

If you have the ability to take TEM-4 directly, you can take TEM-8 in junior year and TEM-8 in senior year.

As long as you have passed Grade 8 before you find a job before graduation, you feel very capable. You can take some other certificates, such as interpretation certificate and translation certificate.
