Ladies, what would you rate me?

I would say that you range from a 7- 7.5, which is good! I don't think its a big deal if she's a couple of years younger or older than you. Try to be friends with her at first, see if you really like her because sometimes all you have is a crush and those tend to fade away. Get to know her by spending time with her in casual group time, like eating out with your friends and see if any chemistry develops between the two of you. Then if you do like her, you can ask her to spend time, just the two of you on a date. Good luck!
