One of my classmates, with a high IQ, sits at the same table with me and has excellent grades. After an extracurricular activity in high school or physical education class, he was sweating all over. If I miss half a class in the next class or self-study, neither will he. As long as he sits in his seat, he can study meticulously no matter how much he sweats. The principle is really strong. I failed in the college entrance examination. I was admitted to Xi Jiaotong University, and I played all the way. I failed in many subjects, so it is difficult to see graduation. My buddy decided to take the postgraduate entrance examination for three months and study at a fixed time every day. As a result, I got more than 400 points directly and went directly to the Chinese Academy of Sciences to study for a doctorate. At present, he graduated less than ten years ago and is already an associate professor in a 985 university.
