If you really don't want to take the math test, you can consider relying on a doctor. Usually you take two professional courses there. If you review carefully, you can also get high marks. This is experienced.
Of course, we need to systematically review and thoroughly understand professional courses, such as our school's teaching plans, courseware, student notes and so on. We should ponder over that knowledge repeatedly, turn it into our own things, and be sure of the whole. For example, when it comes to the change of food in protein (Xie Bijun, the last question of food chemistry in the postgraduate entrance examination of Huazhong Agricultural University in 2007), we can actually answer it from many aspects. I divided them into more than 30 answers, which have something to do with the content of each chapter, because protein and many things interact with each other. This is an example, that is, I hope that professional courses will not be rote learning, but will become my own things completely.
I wish you success in your exam!
