Generally speaking, learning focuses on teaching some answering skills, answering ideas, and the skills and methods of questioners' intentions, which is of little benefit to improving the actual English level. My opinion lies in the improvement of English level, that is, we need to do more questions. Of course, the benefits of doing the problem are not mentioned here. Let's talk about how to review CET-4 with my previous answer about how to review CET-4:

Write in front: for different people, their English foundation is different. To this end, the following experience is for reference only, and cannot be copied mechanically.

Hello! As far as my personal experience (non-major) is concerned, CET test has great hope for people with average English level. After all, CET-4 is simple, but the number of questions is large and the time is short. This requires us to exercise for a long time. We can insist on doing reading comprehension and listening exercises once a day for two or three months before the exam. CET scores are basically in these two parts. Don't try to memorize words for those who have a certain English foundation. As long as you grasp these two parts well, success will be very close. As for the composition, CET reading is very loose, generally 0-0 is not a problem (but you should be prepared before the exam). Late synthesis depends on time. How much time do you usually translate first, and then fill in the cloze (as long as you read and listen in front, you will get 0-0 in the back)

Now let's make a rough calculation: (composition+fast reading): 0+ (listening): 10- 10+ (reading): 10- 10+ (comprehensive): 0-0 = 0-. ....

Finally, I wish you good luck in the exam!
