How to break the directional thinking?

First of all, we should adjust our mentality. Only when our mind is relaxed, it is easier to spread our thoughts. Secondly, the exam is actually a skill with certain skills. The premise of skills is that you can understand and master all your existing knowledge. Of course, understanding is not just knowing a definition, but understanding its connotation and extension, not defining those words. At the same time, you should master its core and essence, so that when doing the problem, you can judge with your own understanding. Divergent thinking needs to mobilize the required knowledge at any time, but when to mobilize what knowledge points, you need to practice. What's more, it is very helpful to grasp the teacher's key points and difficulties, so think along the teacher's direction, which questions can examine which knowledge points, which knowledge points can also be examined, and how these knowledge points are examined in what form. If you can do this, there should be no problem. Finally, I hope you are more confident. Typing the wrong question is actually no big deal. I wish you get into an ideal university!
