Hey, if your parents have the money and are willing to pay for you, then good for them, and great for you!

To the OP, have you checked with the department you're interested in? Some of the students work part time for the department as graders, help with projects, etc.

Edited to Add...

BA - parents & scholarships, few loans
MS 1 - scholarships, part time work, loan or two
MS 2 - employer
PhD - employer while we were in the US and I worked, now my husband pays tuition... am on last semester I hope.

In the US, I was lucky enough to find employers who would send me to school. Full time, the first time and part time for this last trip.
