What kind of experience is it for people with poor grades to take the postgraduate entrance examination?

For a high school that ranked first with a difference of 2 points in the senior high school entrance examination, 3 points in the college entrance examination and 4 points in the postgraduate entrance examination, I initially thought that it was because I was not good at mathematics that I dragged on so many points, so the postgraduate entrance examination deliberately chose to avoid mathematics, and the result was still so bad in the scores of the two multiple-choice questions. I can't blame math. I can only say that I didn't feel anything when I saw the report card, and only one sentence popped up in my mind: I want to be a great person in Sri Lanka, so I must suffer a little first ... Come on, everyone! This is a rare trip to the world. Whether you succeed or fail, don't forget your innovative spirit and pursue the life you want.
