Hey Fraz, it's actually more simple than you think, when you finish class, just approach her, and comment on the class, ending with a question, or make a question right after you get a response to the first statement. But a generic question works best
like "Excuse me, do you know when is the next assignment for?"
Or anything about the class, just think of something you would ask a random person about the class that you might need to know.
Just remember to be chill as if you it were a random guy in the class that you were asking, and be genuinely interested in the question and not in the person.
Continue the conversation ... when you are 30-60 seconds talking just say "Oh by the way, my name is X, what's yours?" Once you get the name, it's done, next time you see her it would be super easy to just call her by name right when you see her, anywhere!
Hope that helps, and let us know
