The postgraduate entrance examination questions given by the School of Mathematics of Haida University are a little more difficult, but as long as you score enough, that's what I did when I was at school. I graduated from the School of Mathematics of Haida University, but I majored in computational mathematics. Now the enrollment expansion, as long as there is no limit, the total score is enough to enter the school. Haida can't recruit enough students every year, and it has to adjust students. It's good to apply for going abroad after graduation from Haida University. Many of our classmates have gone abroad. Prepare well and wish you success!
