I'm an undergraduate biology and chemical engineering dual major student. I recently got into pure math while I was researching patterns in biology which lead me down the rabbit hole of fractals and non-Euclidean geometry and eventually, lead me to number theory. I really enjoy the subjects. Is it possible for me to pursue my graduate studies in pure math? If so, what would be the necessary steps I should take to do the same? I am in my second year of studies and I do intend to take the GRE Math Subject test but I would really appreciate any other advice you could give me. Also, switching majors is not an option because my uni doesn't have a good math program. If you are reading this, I hope you have a nice day ahead. Regards
