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.
