I want to take the postgraduate entrance examination, business administration. I don't know what Gao Shu 3 and English 2 mean. Is it difficult to teach yourself without learning too high numbers? Mathematics itself is not bad. The number of math scores 1, 2, 3 and 3 is relatively simple, but there are many knowledge points for assessment. The simple understanding is that the number three belongs to the third grade, but many children who study advanced mathematics find it difficult to understand. I am a junior this year and learned the number of three. Many people around me gave up the postgraduate entrance examination because I had to take a high number. Mathematics for postgraduate entrance examination is not the same as the exercises in peacetime books, so if you want to take postgraduate entrance examination, you must understand the books thoroughly. But because I didn't learn too much, I should be prepared in advance and have a sense of crisis. You have to take three courses, advanced mathematics, linear algebra, probability theory and mathematical statistics. Many knowledge points are hard to learn by themselves, and they need the guidance of others, so they need to work harder.
