Mathematics should be the most destructive to brain cells. However, if you really like math, you will be very emotional. People in universities often get full marks in math tests. Of course, it's ok if you only do calculations and proofs. Some schools are very strict with theory. In that case, mathematics will be very painful to learn. Generally speaking, the average score of mathematics is the first in the school ... do you understand this? ! Follow-up: Is it easy to take the postgraduate entrance examination after graduation? Will it be easy for undergraduates to fail? Answer: If you take the postgraduate entrance examination, the focus is still on English and ideological and political education. If you want to fail, math will spend more time than other majors. As a science man who has just graduated from college and has no history of failure, I think if you can' fish for three days and dry the net for two days', you will never fail, and maybe your grades are not bad. But it's basically a tragedy that you spend every day online ... you may think it's okay, but in fact, many people can't even do' fishing for three days and drying the net for two days'. Mathematics can't be reviewed until the last week, and the exercises should be clarified every week. Otherwise, I can't find a place in the end ... Of course, the university is not so scary, as long as I spend time, there is no follow-up: Is there a big relationship between college mathematics and high school mathematics? Does that mean that as long as you study hard and change your major, there won't be too many problems? Answer: It has nothing to do with high school mathematics. There must be many teachers who say, alas, what you learned before is nothing. Advanced mathematics! Generally speaking, the base class of the experimental class has the highest rate of graduate study, and the others are basically limited, so it will be more difficult to take the postgraduate entrance examination. If you are willing to study hard, there is basically no problem. If you change your major, you will generally change it in the first semester of college. You'd better ask your seniors when you enter school. Every school has a different experience. Every school has some majors that are particularly stingy and difficult to change, but in general, it is not a big problem to change majors. Of course, it's best to see what others take before you change! Or Tracy's sentence: thank you very much! ! ! !
