I have an app loaded on my phone that lets me study various courses for free. I started studying a statistics course yesterday and today I added one of the algebra ones to review since it's been awhile since I studied it in school. I actually enjoyed the little taste of statistics that was introduced back when I was in school so hopefully I'll actually enjoy that one. I have been and so hopefully it will stay fun. After these, I probably need to do geometry and calculus. I'm nervous about the idea of taking up calculus because I never studied it, but know that it has a reputation of being difficult.
