I Want to be a Computer Scientist
For context, I'm a 15-year-old who will be going into my sophomore year in high school this coming September. For awhile now I've known that I want to follow in my parents' footsteps and have some sort of job that heavily involves programming. My father mentioned that if I want to get somewhere in the industry I should figure coding out while I'm in high school. Currently, this is what I intend to do. I've found out thus far that 1) my high school doesn't have decent programming classes, and neither do any institutions I've found via the gifted & talented organization. By the time I was working on my final project for the C++ unit (in a class that wasn't done by the high school, but was taught by a teacher who worked there), my father looked over my shoulder and basically shook his head at my teacher. I'm currently taking a Java class via Northwestern university, and they've apparently not taught me to program in Java. For instance, when I asked my father a question, he looked at my code and asked me where my "main" method was. I have no clue what that is, and I have about a week of lecture left. I have a couple of friends that are learning from AP review books, and apparently that's a pretty important thing to understand.
My query is this: how do I not fuck up the three years I have left in high school? I know that programming is a career that would suit me decently, but I also know that there are a lot of people leaving colleges with their CS degrees who don't understand the subject matter at all. Needless to say, I don't want to be those guys. Does anyone here have any suggestions for as to how I can do a decent job at learning this subject? I've asked my parents, but they directed me to the course I'm taking now, so apparently they don't know either. There are a couple of things I'm looking at now (Khan Academy and Udacity both have free courses in Python, and I can go buy an AP review book for Java), but I was wondering if any of you had other ideas.
