How do I ask her out? Please answer!?

Maybe she didn't reply because she's busy. Make sure you don't text her constantly.
If you don't wanna screw up just ask her to hang with you and your friends. Ask some people to go to the movies with you or bowling and invite her. Don't make your self sound desperate. Just be nonchalant about it. If she can't go just shrug it off and say we can hang next time. It gives you an excuse to see her out of school and you can show her how charming and nice you can be. She will definitely wanna hang out again with you. Maybe alone next time. You never know. Just be yourself and be patient.
