<p>I actually have an ok background in math (only needed two more courses for a major). They were about the only classes I had decent grades in. I’ve taken all the classes you’ve mentioned including numerical analysis with matlab. I’m fluent in Java, C++, SQL, R, matlab, and VBA. And from AP Comp Sci AB, I also covered data structures and what not. But I’m pretty rusty on pure theory. </p>
<p>I’m considering taking community college courses, but I have two concerns with them. First, I’m afraid the quality of education will be lacking vs me studying on my own. Second, that graduate schools won’t take my grades and coursework in them seriously. So, the other option is taking courses in colleges for non-degrees. Is admission easier this way?</p>
