Generally, if you write it on your resume, you can pass CET-6 unless you have passed Class One of CET-6. You don't need to write a lot of scores, just say that you passed the exam and got the certificate of CET-4 and CET-6. At the sharing meeting, senior brothers with insurance research said that there are more than 600 CET-4, more than 550 CET-6 and IELTS 7.0, which is a good configuration.
Results don't need to be written on your resume, as long as you have a good command of English. Test results are not particularly important.
