Hello, I'm interested in learning math as hobbyist, so I'm not planning to do professional teaching... :) However I'm uncertain whether I should do it via Academia or by myself. I already have a degree in computing and took several math courses, so I have the ability to teach myself and research without the need to attend classes. The problem with Academia I find it's limiting in options for advanced/mature learners, people who already poses degrees in related fields and can learn faster and more efficiently than other undergraduate students. Also, a degree program can take for long, not to mention the high costs of universities. So there's a time and money factor. And unless there's a real and strong benefits I'm unable to see for going to a university, which outweigh the downsides I mentioned, I'm seriously considering teaching myself. Am I on the right track? Thanks.
