How do I start to know a girl that i barely see and is never alone?

[Bumblebee]

Ok. so i go to Milby High and there's this girl that i really like. I have 5 classes each day.On mondays we go to all 10 classes (really 8 since 4th and 5th i have every day) and the days are divided in to "G DAY" And" B Day" 1G, 2G, 3G And 1B, 2B, 3B are really the only classes that are different. Ok sorry got off topic. I see this girl only on G days in one class which is 3G which lasts 1hr and 30mins on Wednesday and Fridays and on Mondays for 45mins. I know her a little since we were in a group project together. But how am i suppose to get to know her if she sits across the room, in assigned seats?!? In lunch I go outside with friends and i see her with her friends but she's never alone. So what can I do? I'm really in "love" and don't know what to do. Sorry my grammar isn't that good. I'm doing this in a desktop and am used to my phone. So please help and answer my question. Thanks everyone. Oh and no facebook.

go up to her at lunch and just say hey there! what'd you think about the lesson?? and maybe compliment something that day while in class before the class starts just to get her attention! even a note would work! you could just put "you look pretty" and get someone to pass it to her, and then go sit with her at lunch and do what i mentioned before. well good luck! i hope i helped!
