Generally speaking, analog paper is used to check for leaks and fill gaps and see the current level clearly. Fortunately, in the future exams, we will not blindly give up some questions, but give a bigger platform for solving the problems that can be solved. Even winning one more point is better than wasting precious examination time.

My personal opinion on the simulation test paper is this: If the test paper of the simulation test is somewhat different from the usual grades, you should consult the teacher, see the teacher's evaluation of this set of test paper, see the merits of this set of test paper, then compare yourself, think carefully about whether you have enough grasp of these, and then make a reasonable evaluation of yourself so as to grasp the future review direction.
