I split a two bedroom with a roommate and we each pay about $440 a month.
Yes, I had GRE scores, but only because I took it at a time in my life when I wasn't exactly sure what I wanted to end up doing.
As for clinical experience, I had essentially none. I mean, I had a ton of extracurriculars and a few of them were medically related, but no actual hands-on clinical volunteer work.
