Best thing to do, is just do you. So what you enjoy, talk to who you wanna talk to. The ladies will come in time.
Best way to start with ladies, in my mind, just wait for the prime moment. Say you about to leave /arrive at school. You notice a cute girl behind you, hold the door open then casually be like " hey" or "Nice shoes" or " nice phone" anything. Then just walk on. That gets their attention, they noticed you noticing them. Ans they also noticed you walking away without really hitting on them. You'll be on their mind all day.
