In your opinion, which school is better and why? I have been accepted to both.
Umiami is better academically an higher ranked but also probably more expensive than Uconn. Go with whichever one you like more. Miami is in Coral Gables near the city and South Beach. I have never been to Uconn but I hear it is pretty isolated, which a lot of people like.
Also UConn is nearly twice the size of UM (19k vs. 10k). Going to a large state school is not for everybody.
What is typically the GPA of students who get accepted into these universities?
Check out the common data sets for these schools. Miami has more kids in top 10th of hs class than UConn (63% vs. 50%) so average GPA will probably be higher as well.
