Students in this major are generally good at mathematics and have a certain computer foundation. You can take math or computer science. If it is interdisciplinary, simply considering the difficulty of the exam, you can take some majors with very simple professional courses, such as management of Beijing Jiaotong University, and only take one liberal arts management exam, or take 3/5 exams and recite them. You can go to school to sell real questions over the years, but the questions haven't changed much in recent years, and mathematics is also the simplest math three.
