Can you believe the fortune teller?

I don't think we can simply say yes or no, because this thing is actually like a monster. Believe it or not. But my point is, you can't believe it, and neither can you. Let me give you a real example: 2 1, 19 years old graduated from high school (excellent grades since childhood). My grades are a mess. The results of the city and province entrance examinations are very good. After the college entrance examination, my grades were a mess, and then I failed. My parents and I are very depressed. But my superstitious grandmother advised my mother to take me for fortune telling. The fortune teller said that I was a doomed person, and I couldn't turn over before 2 1 year old. In order to turn over, I went back to repeat. As a result, I did well in the college entrance examination, which can be said that I turned over in my grades. however
