How to introduce myself to her?

[ReginaldMiller]

Okay so the other day I was in the computer science lab doing an assignment last minute and i was in the continuous tutorial section and i noticed a very cute girl sitting a row in front of where i was sitting and she seemed like she wasn't a comp sci major just taking on class sorta thing you can usually tell in there haha i myself am not a comp sci major just needed one class and anyways the girl and i shared a few glances as she was looking back for a tutor and i caught her looking back at me with a smile a couple times too people kept coming around her helping her with her program and stuff so i didn't feel right to go over not to mention i had to get my assignment done. So my question is if i ever see her in the lab again how should i approach her cuz i definitely want to get to know her and i don't really know her degree program so i cant assume she is in the same level class as i am. Cuz i was thinking of being like oh hey ur working on that too blah blah but yea wats a good way to meet her and get her number to meet again outside school.also if it makes a difference important a brown guy and she is a brown girl, i think it sorta does just cuz naturally i notice only brown girls check me out and where important from they only seem to be interested in brown guys
and sorry by brown i mean south asian like indian or pakistani i cant really tell, but me im punjabi, indian
Or could she have been looking at my mustache haha
