It sounds like “what’s the cheapest vehicle to buy?” Do you want a sedan? a coupe? an SUV? a pickup truck? an 18-wheeler? diesel? electric? hybrid?
What “graduate” degree? What field? PhD? MA/MS? Some offer PhD programs, some don’t. Some don’t offer terminal MA/MS for some majors.
It doesn’t matter if the school is easy to get into if it doesn’t offer what you want to study.
