Iowa state vs Ohio U

Hi with the number of scholarships I have received from both schools Iowa State would be 5,000 more a year and 20,000 more in 4 years.

However, for Ohio U I have to keep a 3.0 and Iowa I have to keep a 2.0.

I don’t really know how hard it is to maintain this GPA. I can afford both but I’m questioning if Iowa State worth 20,000 more for engineering or business
