Location: Ohio and Indiana are both Great Lakes with similar climate, but Indiana is closer to the center, and I personally think Ohio is better.

Professional choice: Purdue's projects are really good and have advantages. However, if the landlord changes to a major, we should be cautious, considering that Purdue's colleges and universities are ordinary except Engineering College. This is one of the reasons why Purdue ranks 6 1 in American news rankings.

Number of students: If it is Columbs, it is indeed the place with the largest number of undergraduates in the United States. It seems that there are more than 50 thousand people, although there are many 40 thousand in Purdue.

Learning atmosphere: Purdue is a famous gathering place for compatriots. You won't feel lonely here, because every major can find familiar figures. PS: As for the difference between TOEFL 79 and TOEFL 88, it can really reflect Purdue's engineering advantages, but TOEFL is no longer the decisive basis for admission to a good school. UIUC TOEFL 79 actual admission 100+.
