How to start convo with random girl in my year to get her to like me?

Do you have mutual friends? You can always start with "hey aren't you friends with so-and-so?" and go from there. If she's near you just make a comment about something around you, like something someone just said or something. You can always strike up a conversation over social media. You can even just flash her a smile. There's also nothing wrong with asking about the homework - that's actually a pretty good way. Or you could ask if she's ever taken a certain class or teacher because you're thinking about taking it or you're struggling with it, etc. Asking for the time is a good excuse, too. I had a cute guy ask me that yesterday claiming he didn't have his phone even though I saw him with it before class haha
