Welcome

About being 16 - I also started Robocode when I was 16, so nothing to worry about. I'm not sure how much trig, linear algebra and parametric equations you've done, but for me Robocode was something that taught me more in these fields than school did, quite aside from all of the artificial intelligence stuff. So you've probably got a steep learning curve, but nothing you can't handle, I'm sure. Welcome! And if you have any questions, just ask =)
