Flight Tickets = Depends on how much flying you do. Some people commute to school via plane, some do international trips, and others do neither
Commute to School = Depends on how far away you live and what kind of car you drive
Stay = Depends on what city you live in, how nice of place you live in, if you have roommates, etc..
Other Related expense = depends on the school, where you live, and how active you are in the school, and what your school requires.
So in other words, there is NO way to estimate without knowing your particular situation.
I would however contact the school you are looking at and ask them. Often times they can give you a rough estimate. I would add another few hundred or more a month to be on the safe side. Also, if you are questioning how much it will cost, realize that it is a significant expense and you should start determining potential costs right now. Research and figure out how much you will need, b/c you don't want to end up on a mac n cheese diet for years. Good luck
