Can parents claim me as dependent? I graduated college and now working FT (23yo)

(23 years old) I WAS full-time student Jan-May 2017. I worked part time while in school. I now have FT job (started July) and earned 60k total. We still live under one roof the whole 2017, but I provide for myself. I also study part time grad school, which I pay for, since August.

I'm trying to help my parents increase their refund. Can I file my taxes as dependent, and can my parents file theirs jointly and add me as dependent? Whom should the college information, 1098T and 1098E, be put? What if I paid for those loans?
