The high number of freshmen is basically the most basic from trigonometric function, integral and differential.
It is equivalent to the level of high 2- high 3 in China ~
The advanced mathematics level of Korean universities is equivalent to the level of freshmen in our domestic universities last semester ~
Of course, in my sophomore and junior years, Korean students will also take courses such as industrial mathematics, which I have never attended. I don't know how it is ~ it is said to be difficult ~ but if you enroll in Korea, you should be able to keep up with the progress.
The premise is that you have to learn Korean well, or you won't understand it.
