<human>: Can you condense the text into a few key points?

Hello.
This is my first time posting this question.
I'm completely socially awkward person with not the best looks.
(2m 90kg).

There is girl from my university I'm seeing only once / 2 weeks.
She is also socially awkward. Doesn't talk with anyone. The time I see her (3hour lecture) I talk with her (No, we are not interrupting anyone).
There is no other contact with her. She gives her phone number to noone.
She never responds to any Facebook messages and never posts anything.

She lives in the other city (30min drive).

I'm really the only person that talks with her. I tried to ask her out but she never says yes or no. She needs to think and let me know. Never lets me know.

She has university laboratories Thursday 8:00 - 13:00 CEST time.
I have job 8:00 - 16:00 that day but I can skip some hours.

Is this good idea to get to university earlier and give her coffee when She enters?
Or wait around 13:00 outside university and ask her for coffee here and now?

I know those question do sound stupid. But I'm completely clueless. I was never interacting with society. Interacting with more then 1 person at the time (parties) makes feel uncomfortable.

I have no idea. I have never had girlfriend my entire life ^^^(It was like one girl but it was Hollidays away from home and we ended up in adjacent hotel rooms with broken door between rooms for 2 months and free alcohol).

I don't know how to talk to her. I desperately need your help. Anyones help.
In 2 months there is possibility I'll never see her again (End of university)).
<bot>: There is completely socially awkward girl I'm into. I'm even more socially awkward. I see her once / 2 weeks. No other way of communication. What to do?
