1- Try to find out what both of you have in common and start a
topic from there.
2- Got reply SMS better than no reply at all. be patient,
pal.
3- If you can't wait for her replies, why not call her and have a
chat over the phone?
4- Sometimes, it's better not to be in the same school. Trust me.
You will have more difficulties trying to get close to her if you
are really a shy guy.
5- Be more thick-skinned.
6- Pick up tips from your friends on how to dress up.
7- It's not about looks. Some girls would prefer an ugly good guy
than a handsome jerk. I don't know about your gal. You just gonna
treat her well.
8- Be a gentleman. Pay for the ladies.. if you are broke, suggest
to go dutch. Sometimes, you don't have to spend alot to woo a girl.
etc, go to East Coast in the evening, get some sandwiches, snacks
and drinks from 7-11. Find a good spot, sit down and have a chat
with her. It's less than 10 bucks.
You just have to do the right thing at the right time.. Create
opportunities for yourself instead of waiting for things to happen.

Good Luck, Pal!
