Advanced mathematics is a public course, and everyone who studies basic science or engineering should take it. The importance is average, but the ability of logical thinking is cultivated. Learn if you can. If you are not good at math, just make sure you can pass 60.

As for undergraduate pharmacy. Different schools have different arrangements because of different teachers, and I don't know which pharmacy you are in or which medicine you are divided into. Medicine? Still medical? Wait a minute. . . If your major is pharmacy. Your undergraduate course should focus on pharmaceutical analysis, medicinal chemistry, natural product chemistry, pharmacognosy, pharmacy, pharmacology, toxicology and so on. I hope my answer is helpful to you. . .
