Hello, I am 20 years old and I currently hold a bachelor's degree in law because of various reasons and causes ; however, what I wanted to study was mathematics. And I currently wish to study it but I lack all the prerequisites to apply for a major, as I have not taken any calculus classes. Three questions : 1. Is there a way for me to somehow get those prerequisites? 2. I am bad at mathematics - I usually had grades that floated around the 70-75% - ; but with work is it possible to do well? 3. Is it also possible to not do a major and simply do a baccalaureate consisting of only mathematics?
