When I was in college, because many students were taking CET-4 and CET-6, for me, if I didn't pass CET-4 and CET-6, I felt my English level was very poor. In this case, I also began to review CET-4 and CET-6, so my current English level is ok. I think if I set Band 4 and Band 6, many students will compare with each other. Some students passed CET-4, while others passed CET-6. For those, this suggestion will be a reference for some enterprises when recruiting.
Just like our English level, some foreign trade companies will definitely require English to pass CET-6 when recruiting, because for them, if a student's English is not even CET-6, it is difficult to communicate with foreigners, so it is not necessary. Therefore, I think this suggestion of math and physics in CET-4 and CET-6 can also be beneficial to some enterprises when recruiting. For example, in some biotechnology companies, if someone doesn't even have Grade 4 in Mathematics and Physics, then this. This suggestion can give us a standard to measure ourselves.
Just like when we were in junior high school, many students thought that there was only so much knowledge of mathematics and physics in the world because we had little knowledge of mathematics and physics. In fact, if we have the standard of CET-4 and CET-6, we can know that our grades may have reached CET-4 in junior high school, but they may have reached CET-6 in senior high school, and there may be a high standard in the future, so that we can know what kind of level we are in mathematics and physics.
In short, with the development of society, more and more children have received education. We have CET-4 and CET-6. Now we have to set up CET-4 and CET-6 exams in mathematics, physics and chemistry. I think this is very good, because on the one hand, it can make each of us pay more attention to our math and physics achievements and strive to improve. On the other hand, it also helps some enterprises to select talents when recruiting. Of course, for us personally, we also have a standard to measure our achievements.
