CET-4 and CET-6 are held twice a year in June and February. Theoretically, you have eight chances to take CET-4 in four years, but some schools stipulate that you can only take CET-4 in your sophomore year, so you will miss two chances. In addition, many institutions stipulate that candidates who miss the exam after registration will be suspended from the next registration. Only college students can apply for CET-4 and CET-6, and those who have graduated can't take CET-4 and CET-6, so it is recommended to review them in a down-to-earth manner and pass them at one time, because it takes at least two or three months to prepare for each exam. It's a waste of time if you take more exams. You must make full use of your time.
