I'll give you a brief background as to what has been happening. And then you guys can then give me your advise.

I have attended 13 weeks of uni and now we have one week of study break before the exams commence.
For the first 4-5 weeks i sat down beside a girl, maybe a hb7 or 8 in many ppls eyes but a look that appeals to me more than the typical hb10 look. We spoke only in the first week and after that it was 4-5 weeks of silence.

However, suddenly one week when i entered the classroom, she was sitting alone and she shouted "Hey, How's is going". So we started chatting. Typically around uni stuff. For the remaining 6 weeks we chat before classes start and after classes end, we walk together to our cars across the road. Last week i suggested that we exchange contacts as it may be useful in helping each other for the exams.

She gladly accepted and took down my number and gave me a missed call to give me her number. Well, I think she's a nice and down to earth person. Before entering our cars, she shouted to me from her car that she will text me with a study plan.

I was wondering is there anything i can text her now?.. Im really bad at this sort of stuff guys. I'm very goal driven and am typically a straight forward person. Any advice on what i should do??
