Back to college and the pickings are nothing but slim. In my pyschology class yesterday i encountered this gorgeous brunette with glasses, sophisticated and well, she's 21

. Lots of pluses. I first saw her from across the class and i was captivated. Its the first week and we did introductions and what not. I introduced myself well and i think i came off as funny and intelligent - my best 2 redeemable traits. She seemed organized and mature. After class i asked if she'd be my note buddy(exchange notes if one of us is absent)and i threw "study buddy" in there too to test the waters. She oblidged to give me her number and email. I was cool and collected like i usually am when opening/closing.
So here is where i stand, she gave me her number, nobody else. IOI. I gave her a little bit of game but i think i messed up in getting too caught in her age and ability to buy alchohol. I think im supposed to just act like a study buddy at first, get to know her before anything else. I wanna call her but at the same time i usually screw my mid game up. Granted its better to have "loved and lost than to never have loved at all", however im straight up scared to make the call and when it comes to us meeting im too nervous. I hate screwing up my mid game and im looking for some pointers. Perhaps conversation wise, being a little bit flirtatious without overdoing it and being a little bit serious but not boring. I am horrible at finding the middle ground. Im either hella excited or hella mellow, too happy or too insecure.
Anyways, i think i want to call her tomorrow and ask if she wants to meet for coffee over the weekend and "talk psych". "i wanna get to know you if we're gonna be study buddys". I was thinking of prepping myself on this weeks syllabus beforehand so i can guide our session so to speak and not have to think much about it. I'm thinking coffee in the late afternoon. Is it bad per se to try to meet up so soon? Being rejected once, i might not be as opt to ask again o.o
Negs/worries: i ride a bike - can be seen as a bad thing. can barely afford to buy her coffee and im not the best at carrying a conversation. her looks are so intimidating - hopefully her brain(which i have yet to get to know) draws my attention away from her rocking body hehe. I cant bring her back to my place to hang out because it's my aunts place and she says "no friends"
neutral: i have plenty of cigarettes, if she smokes its cool, if not im a bit of a self destructive bad boy. im fine with either, or. i have starbucks gift cards which i cant imagine being a bad thing.
positives:the ball is already rolling. i just need to push it along and i have you guys to tell me how much pressure to apply. until next wednesday, its unlikely she'll make any other study buddy's for this class. i saw other guys pissed that me, the alpha, got to her first and im sure they'll introduce themselves wednesday so i better get ahead of the rest of the game right? I have that good old kung fu physique and i dont look half bad...
tl;dr - do i take a study buddy out to coffee just days after meeting her? do i draw attention (peackock) to my current lack of funds and social status or do i direct her attention away from it? Do i talk more about her or more about me? Do I open up so as to allow each other to evaluate psyches? Do i act more friendly or more flirty? Do i stop worrying so much and try not to develope oneitis? (lol just added that after reading everything - i really am worrying too much, hopefully u guys can help with this) And lastly do i try to plan everything or try to stay in the moment and go with the flow? Its in my nature to try to organize it all[hence why im here]...

thanks for reading this far
