Austin T.’s Answer
To continue, I think we need to define what a university is compared to a school, in terms of higher education. This should help provide a better understanding for the remaining of my post.
A "university" is a group of schools for studies after secondary school. At least one of these schools is a college where students receive a bachelor's degree.
One thing to consider, just because the university is the best, does not mean that the engineering school or specific engineering school shares the same ranking. For example, I went to a top 100 US university, but they were ranked number 1 in the nation for their school of journalism." - https://www.studyusa.com/en/a/107/what-is-the-difference-between-a-school-college-and-university-in-the-usa
So to answer your question, search for the best school of engineering (I would even narrow the search down to what field of engineering) you can get into, or a school of engineering you want to target (depending on your current academic year.) But don't freight if you are not accepted to the best school in the world. There are plenty of successful engineers from all different educational backgrounds, just try your best!
