Is it possible to go from art school to a graduate school in mathematics?
I am currently a 21-year-old university student. I studied for two years at a university of science and technology, but the level of the university was not high, and I could not master discrete geometry and graph theory, which I wanted to master, because they were mainly engineering mathematics. I decided that I could not do advanced research at the graduate school of this university based on my professor's words, "Advanced research is not possible at our graduate school.
I withdrew from the university and enrolled in a correspondence course college in April of this year as a means of entering my ideal graduate school, but the content was completely different from the level of mathematics I was looking for (e.g., it only dealt with elementary algebra). Therefore, I am considering dropping out of this university as soon as possible.
I have always been interested in Western art and computer illustration as well as mathematics, and I was planning to take painting classes at the same time after being accepted to graduate school, but after receiving this offer, I decided to spend my bachelor's degree in computer illustration rather than studying at a boring university. And at the same time, I plan to attend a math tutoring school, and in the future, with the support of an instructor with a graduate degree in mathematics, I plan to enter graduate school in mathematics and become either a university professor or a (web) designer who uses discrete mathematics such as combinatorics.
All in all, am I making a reckless choice? I want to at least go to grad school, so I need advice on three main points.
1,as someone with a background in mathematics, is it difficult to go from art school to graduate school in mathematics?
2,are there any other professions that use discrete mathematics other than the ones I mentioned?
3,how much would it affect my career if I dropped out of my current university?
Any other advice would be appreciated.
