You're never too young to learn the basics like kino, escalation, body language, the women's mind and the philosophy behind pick up (f.e. "why do girls like leaders and not just looks?", "why neediness won't work", etc.).
But when I just learned the game and mm, I tried to use it on 18 year old girls of my school, but it failed, with the consequence that I sometimes made things worse or that people saw me as an arogant jerk. If I neg them they're offended, if I ask them "what is your greatest passion? And how do you feel when doing that?", they say to me that I ask freaky questions.
So be good at the basic stuff, and be natural for the rest. Having a great social status and being fun is important between the age of high school and 20 years old. After girls pass the 20s, things will change.
And yeah you can make out at parties but getting one night stands is even difficult to get from 19 years old girls, let alone 15. So focus on relationships or make outs at silly parties.
Btw, you say you live in the United Arab Emirates, but is it actualy allowed to play, kiss, fuck,... girls and to have girlfriends there
