Find excuses to talk to her, ask her for help in a certain class you have with her, ask if she's looking forward to any new movies coming out. Compliment her(just not too much yet cuz some girls may feel its creepy) become friends and see where it goes from there. Good luck!
Ask her if she wants to hang out if she says then she isn't good enough for u and if she says yes then she is very smart, if you are to shy to ask her out then pass her a note at class or lunch which ever is best, if u can't do that either then complement her and in the future that might lead to somewhere , if u need anything else to know go to my hey crowd page, ask a question on the teens file and I will answer it for u. 1 more thing , ask if she would go on a date with u, if she runs back to her friends than that means that she likes u and that is definitely a yes I will go out with u <3
Find out wat she liks from her friends lik wat she likes in a guy or wat she likes thm to wear then do thos for a while i had a boy friend once and it was love at first site but i have a crush now and i think he is in to me becuz i did all of these things and they work good luck and if u dont want to do my advise thn just be ur self good luck with her😀
