I was accepted to UMDNJ as an out-of-state (NY). In-state tuition is around $21,400 (from Class of 2009) and total including expenses, books, room+board, etc. is around $53,000. Out-of-state tuition is $33,500 BUT as long as you establish residency in NJ right away (I think deadline is August 2006) by having/renting an apartment in Jersey, changing plates on your car to NJ, etc. you will be an in-state resident for the fall, unlike other states such as NY where you have to live there for a while before establishing residency. So pretty much all of the students can become in-state right away.
Hope that helped!
