A very pseudo-scientific thing about me, is fortune telling really effective? 、

Judging from the current scientific level, fortune telling is not supported. But we really can't explain some phenomena now.

I think what you said is mainly coincidence. The reason is: 1. You always think you can't pass the exam. You failed the exam three times. Of course, you didn't plan on it this time. You have lost confidence, so subjectively, once you pass, you will feel even more incredible. You have worked hard for so long, you might as well fool around once, and your heart will be unbalanced. Then, you will find an explanation that makes you feel reasonable, so as to make yourself psychologically balanced. And the fact that your mother told your fortune gives you a reasonable explanation.

I've had a similar experience myself. I don't remember the rest. One small thing: I play games seriously and work hard, but I can't pass. Then I washed my hands, went to bad luck, played again and went blind. I really passed. Sometimes, this is a state of mind, you don't care in your heart, but you succeed.

That's what you thought when you took the exam: you are bound to fail this time. Just do it casually, and your heart will be relieved, so it doesn't matter. Your subconscious will guide you to do the problem, but you will do well in the exam.
