U of Minnesota vs Penn State University vs Purdue(chemistry) + Decline!!

[Juuuuun]

Hi guys,

I was majored in chemistry in college and I interested in synthetic chemistry(Organic chemistry).

Fortunately, I have been got offers from U of Minnesota and PSU, and I am waiting for the result after interview with Purdue.

Since those schools have similar US new ranking, it is hard to decide where I should go. 

As international students, I have limited information about this.. 

Please help me!!! 

 

+ Yesterday, I sent decline letters to U of Arizona, Iowa State University, U of Pittsuburgh. Good luck to all !
