Iowa State University engineering is very good but I think you’ll need stronger grades to be admitted because you’re an out-of-stater. And for better or worse, some have characterized ISU as a weed-out school.
Be aware that as far as future employment is concerned, engineering can be very regionally focused. Yes, some schools attract “national” recruiters, but at many regional companies dominate the career fairs. For example, UTC, a major technology/engineering firm, does most of its recruiting in the Mid-Atlantic and New England states neaar its Connecticut and New York State base. Other firms, such as Ford Motor, Microsoft, Boeing, General Mills and ConAgra recruit nationally, for obvious reasons.
For a ‘B’ Student and aspiring engineer on a budget, I would suggest these schools for Mechanical Engineering:
SUNY New Paltz
Clarkson University
Worcester Polytechnic Institute
Cleveland State University
South Dakota School of Mines
U of Rochester
Rochester Institute of Technology
Texas Christian University
Louisiana Tech University
U of Tennessee-Knoxville
