Housing questions.

I was wondering if I need extra long twin sheets for the beds or if regular sheets will be fine. I have a set of extra long for school so it doesn't matter much, but I would like to know what I need to bring.
Thank you!
I can't wait until I process in on May 13th.

I think they are just regualr twin beds. I brought twin XL though and they aren't overly big, they're fine
