Can't find an opportunity to talk to this young woman at all?

Hi

Met this nice young woman who s doing two of the same subjects as me at university, bit of info, I m 24 she d be probably be roughly 21 if I had to guess?

Had a bit of a chat to her after class about two weeks or so ago, just a quick chat about degrees and subjects etc, but I d like to talk to her again if possible.

Problem is I don t know her name yet :/ and for the last two weeks I haven t seen her in any lectures or anything, so I can t find an opportunity to talk to her.

What do I do, there s only a few weeks left in session and after this I m more or less done with my degree?

Thanks

As the title says, having trouble finding an opportunity to talk to this woman at university
