Woo hoo! I am in my last year of graduate school! 
Congrats! Are you pursuing an advanced academic degree?
Yes, I am. I am just wondering though, how many graduate schools there are in the US. 
Many universities award graduate degrees, probably hundreds in the U.S!
Wow! I wonder which one is the biggest. 
Harvard is, an MSc or a PhD in epidemiology from there is quite big. 
I wanted to go to Harvard, but couldn't afford it. What else can you tell me about graduate school?
Well, specialized advanced degrees in professional fields is probably ideal to earn high wages.
Neat. Anything else I need to know?
Graduate school
A graduate school (sometimes shortened as grad
school) is a school that awards advanced academic degrees (i.e. master's and doctoral degrees) with the general requirement that students must have earned a previous undergraduate (bachelor's) degree with a high grade point average. A distinction is typically made between graduate schools (where courses of study vary in the degree to which they provide training for a particular profession) and professional schools, which offer specialized advanced degrees in professional fields such as medicine, nursing, business
Doug Anderson, 1995 Kate Tufts Discovery Award recipient, remembers her sardonic wit when meeting her that year: "She came into the room at the Claremont Graduate School grumbling that she couldn't smoke in there, and then she stopped and looked at Tom Lux [that year's Kingsley Tufts award recipient] and myself. Kate Tufts looked at us and said, 'You don't know how glad I am that this year's awards were given to a couple of really disreputable poets.'"
Judging.
