I never took statistics or linear algebra. Only AP calculus. So when people refer me to academic papers (or even Wikipedia most of the time) I'm not able to understand it.
I can study on my own, and have been for stats/probability. But started asking myself, why not just get a degree and make it quicker. I'd have to leave my job for a number of years, but then I'd be able to study all day instead of nights/weekends.
