How do you ask out a hot quite popular girl when you are shy and not as popular as her or talk to her much in ending of 7th grade?

Well In 7th grade, if you are really shy then practice not being shy talk in the mirror, think about talking to that girl, and stuff like that. If she's not really popular, but has a lot of friends then become friends with her friends. She'll start to notice you if you are friends with her friends. And it's also good to have her friends approval of you because they might set you two up.

Be nice to her, and don't flirt with other girls because she will think you are not interested in her.
