Do you go to a specialized school? If only such classes were offered here. I too am a high school senior but everything I know (little compared to you) is self taught. I am looking to college to supplement that.
Most of what I know is also self taught. Once you get into the more advanced CS classes at my school, it is very independent (I am the only one in each of my classes this year). I can ask the teacher for help on an assignment or have him explain something if I need him too but most of the time I work independently.
I went to a public school that had a programming track like Spencer but we started at BASIC and ended in an "advanced" C++ class.
I jokingly referred to our classes as learning "skills" since we lived so close to the poverty line. We had well taught and well funded tracks in dry cleaning, construction, cosmetology etc. I joke but they provided job placement and it probably gave many people a decent living.
I also remember how great it was have an army recruitment office inside the school.
