There is no level one or level two. If you are a junior college student, start from grade three. If you are an undergraduate, congratulations, just take the CET-4 directly. The third grade is very simple, and the junior high school level paper can be passed. Band 4 is not particularly difficult, but you have to do a few papers to accumulate experience, because the score of that band 4 is very different from that of high school, and the questions are very poor. That's all. I hope to adopt it, thank you.
