VERY VERY easy if she's cute! Do what you do haha =)
The rule is this: Are you cuter than the guy is popular? Is your value higher than his or equal? If so, you have a greattt chance of dating!
HOWEVER, dont OFFICIALLY ask him out! Thats a little weird, and he might say yes but the conversations you 2 have after that fact might be so awkward that both of you kinda go "yeah, no, this isnt working."
Instead, talk to him about school, sports, or ask him a social question! For example, "hey i need your advice would you rather a girl wear high heels or tennis shoes on a first date? Whats the best?" and just be like "yeah its for this guyy haha sorry" then act like your just trying to be nice but you actually kinda think he is too, and be like "haha but your kinda cute too! So whats your name?" And then just go from there.
With girls, you have to have a lottt more tact and you have to tease them, neg them, win over their friends, create jealousy, show your high value and popular and fun with OTHER people not just them, etc etc.
with guys its incredibly easy.
and after that, just go to the movies ro whatever
