Going on a date with this girl...?

I met this girl at my sisters bday party and we flirted the whole night. I got her number and asked her out to dinner. I'm really nervous cuz she is a college grad and I'm still in community college (she's 22 and I'm 20). She already has a high paying job 20 dollars and hour and works like 50 hours a week. I only make 10 and 11 dollars at my two part time jobs but I have managed to save 17 k so far. So it not like I'm a bum or anything. Does it matter that I haven't finished school do girls care? I think I'm smart. Do you need to have equal degrees in order to date a guy or does that not matter. I'm hardworking and work 30-40 hours a week
