yup paree is right. . Unless you are from very reach family or u get a scholarship(at least 60-80 %), don't even think to come here. You might think that its our "pull leg" startegy but its a bitter truth that all of us (including me, no offense please) end up cleaning the toilet and washing dishes over here. Just finish your undergrad first with very good GPA and have a good score in GRE before coming here.

All the best.
