i know a lot of people who can make openers and such
im starting out and dont how to make ones for a school setting

For school?

If you don't know them:
"hey, Who are you?" or something along those lines.

If you do:
"hey. (Then state an observation about them)" or "Hey, how was your weekend? The craziest thing happened..."

As you can see, these aren't creative or 'PUA-like' at all. It's about delivery and having a strong frame.

I wouldn't use opinion openers ever in high school, unless they were really relevant and situational. Just be cool, friendly, and outgoing. You can still save them in the back of your mind for times when you are in isolated sets of girls that you are talking to. That way you can lead the conversation as well as any DHV spikes or whatnot you have in there.
