A lot of the stuff here applies to all age groups - mostly the self-development and mindset material, which is the backbone of seduction at any age. I would start there.
If you're interested in getting laid in high school, you'll find some of the stuff here doesn't quite apply. Daygaming, for instance, will likely result in lower results because most women in your age group are hesitant at getting stopped by strangers in public, and for good reason. It's certainly possible, but I'd focus your efforts elsewhere. Work on the mindsets especially, and try to cultivate a mature sexuality that most men your age won't begin to grasp until later.
The vast majority of your potential right now is in social circle. A lot of the stuff the college age guys are trying out should work in high school with some modification. Be well known, have a great vibe, and focus on being genuinely sexy. Most high school guys suck at that, and most high school girls don't get good sex until college or later as a result.
