Regarding the third part, I agree with you. If you work hard enough, it's easy to get high marks.

It's really not easy to get high marks in the entrance exam. This year's composition should be graded. Even if it is completely stuck, it is not bad. Deduct nearly 30 points, which is equivalent to saying that the full score is 170, and directly subtract 30.

As for mathematics and logic, according to the forum, like an IQ test, it pays more attention to people's thinking flexibility and logical ability. Some people can do well without reviewing before, and after a period of practice, they can basically not deduct points. Some students have been reviewing for a long time, but they have never been able to touch the doorway. The deduction for logical mathematics is tens of points, which is really out of proportion to their efforts.

I suggest you find a set of real questions first to see how powerful you are and whether you can adapt to this method of testing logic. If you are not bad, choosing comprehensive can save you a lot of time.
