I never went to college; no one in my family has. I have a fascination with computing (at least I think I do), but the more I learn the more I feel like there are missing pieces of information. I think a formal education would help me to know what I don't know I don't know. Here's the thing: I have no clue where to start. I know there are prerequisites for computer science, but do I take it upon myself to take those courses, or do I go ahead and apply to a college and the college will have me take those courses?
Note that I intend to earn this degree online, and have not yet chosen a school; I hold a GED, not a high-school diploma; my math is only as far as pre-algebra; I'm about to turn 31; and, earning this degree really isn't about getting into a new career (that would be a +), it's more about being able to bring some ideas I have into fruition and being more self sufficient. I'm not concerned about debt.
So, I would really like some advice on how I should proceed. I would also very much appreciate any personal opinions regarding any of the above details. I'm open to constructive criticism, so don't hold back thinking that I will take offense.
