Do you have any skills in studying mathematics in the postgraduate entrance examination for foreign trade and economic cooperation? I'm not a trade university. Which counseling institution should I go to? Actually, I majored in mathematics, so I haven't studied mathematics much. As a result, my math score was average. Although I was finally admitted, I was desperate. The suggested topic is down-to-earth. I studied in Kaesong, where most of the students who took the examination of trade universities were non-trade universities, and the teacher's explanation of mathematics was still in place. If I had listened to my teacher, I would have done better.
