Which school is better for biomedical engineering?
They both cost about the same for me.
Rutgers and UConn are both very good state schools for engineering. Have you visited? Which one do you like more? Do you need to be close to a city or do you want a more quiet setting? You can also do more detailed research on their programs on their respective websites.
These are the questions that should be a factor in your decision. Congratulations on your hard work, and good luck w/ your decision!
