No, no, no. Don't say that at first. Be like, Hey, how's it going or what's up? and ask her if she remembers you. Then ya'll should start talking pretty good from there if not, hey, try and try again to talk to her.Is this a good approach ?
I suggest you take the direct approach. Ask her if she's seeing anybody and if she responds in the negative ask if she'd like to go out with you sometime. If she saids yes....ask if she's free on a specific date and time and follow through. Good Luck
