Is it weird to add a fellow student on instagram that I found after searching for her name?

So in university, I had a course last friday and this monday and there was a woman that I found really interesting and attractive.

However because it was a just a two day-long seminar and I mostly talked to my other student friends in the breaks, I had barely any contact with her.

She was sitting two seats besides me and we exchanged some words but nothing special and there was no situation to ask for her number.

Anyhow, as it was a one-off seminar, I'll probably never meet her again. I know her name tho so I looked at the instagram of my student association because most of my fellow students follow it and typed in her name.

She came right up but now I don't know if I should just add her. Is it weird adding her when she never gave me her number or instagram and we barely talked in the course?
