If you want to review, you might as well study. Reading vocabulary books of CET-4 and CET-6 is the most basic. Of course, you can do some reading, which is an important aspect of keeping your hand feeling.
Of course, I personally think that listening is the most difficult part of this placement test, because listening is not required in the college entrance examination in some places, and teachers in universities will give listening training, so I suggest strengthening listening!

The placement test for freshmen English is very important, which determines whether you are qualified to refer to the National English Test Band 4 and Band 6 in June+February, 5438.
Many universities take English exams when freshmen enter school. According to your different grades, you are divided into ABC classes, and your grades are sorted from good to bad. The ranking before and after determines whether your English education in the next four years is good or bad. If you rank high, it means that your English foundation is good, and you will have the best English teachers and the best textbooks for you to choose from. Of course, you will be required in the strictest way, but high standards will lead to high progress.
