How do I approach this girl from class?

Ok so the first thin u need to do is not make it too bvious that u like her and tru to be friends first. Just go and start a conversation abiut anything; teachers at school, classmates, how stupid u think Justin Bieber is... It could be anything. If she looks suspicious say she seems to be interesting and you just eaana know why everyone says shes so awesome. Say you know countless guys who have crushes on her and try toget her to make you tell her who. She's bound to want to know. Try to fund the things she lokes and dont be afraid to be a bit cheeky. Try to find things you dont agree on as well as things you habe in common. It always cute to have discussions about things you disagree on. But whatever tou do DONT LIE ABOUT THINGS YOU HAVE IN COMMON this is the biggest mistake ever because you wont be able to keep teack and you'll either forget what it was or she'll know what you're up to.

When she's just sitting in the class, walk up to her and lick her face. That will get her attention for sure!

Just ask her sometihung class relsted or homework help.

By asking her to give her phone number

Tell her something like"how were your grades?then she will answer and so on.try to keep her talking to you.
