I really like this girl, but how do i go at it rightously?

so i finally mustered up the courage to speak to a girl in class. I really dig her alot. we have same interests and such. we have been on 3 dates so far, and yestered was our 3rd. We went out to eat and a bar after. I actually danced with her and im not much of a dancer,but let me tell you i felt alive. She is sweet, funny, actually pays (which some women dont) and i find that a big turn on. She looked breath taking! like big time. but i want to keep dating her but i dont know how to go about it. ive asked her out again and she said nxt week, so yeah. i just dont want to mess it up. any advice on how to go at it and maybe land this dream girl?
