I'm a high school student who loves computer science. I've studied different languages, paradigms, implementations, etc., and of course proper program design.
I'm not much of a graphics guy but CSS seems to be my forte (possibly because I try to do everything I can in CSS instead of Photoshop)!
My pet peeve is people who ask questions obviously beyond the current lecture to try to impress others. (You wouldn't ask about integrals in a pre-calc course so why would you ask about multithreading in the first lecture of a basic programming class!)
