Based on the people I know who went in random, it’s alright… I know a good deal more people who ended up with roommates they were friends with than roommates that were horrible.
Some tips tho:
Unless you’re really super messy/don’t mind mess, don’t say that you are moderately or very messy. I ended up with a roommate who was way messier than I was and it got very frustrating. Apparently everyone knows that you are supposed to over exaggerate your cleanliness? (unless i guess you are really messy and are worried you might offend your roommate with your mess)
You can always pick a roommate at orientation if you meet someone there that you like. The window to pick a roommate for freshman is pretty wide so most people go in random but then some people find roommates through facebook groups or orientation, so keep that in mind.
Everything else… just be honest about what you’re filling out and you’ll have the best result. I hope that’s helpful!
PS if you mean you are going random and aren’t a freshman, disregard this notice because that’s a whole different story.
