i need help

Ask her about things she likes, like music or video games. If you hit upon something that really intetests you it will be a lot easier for you to talk about it. You can talk about food, tell her about something you had recently see if she likes it. Everybody likes pizza if she doesn't like that, she's not of this Earth and probably evil. If she doesn't like pizza inmmediatly run away as fast as you can!

ask her about her course and what she wants to do after graduating

Ask her if u wanna go for a bite to eat , simple as that !! If Yesss then u get to talk about ur homework and if she says no then say no worries , maybe another time !! Simple as that , what's the worst that could happen

I should have added if you can find things that interest you to talk about you can just relax and be yourself, it will be easy then!
