A ranking of 31 is NOT low. There are thousands of universities in the US. Do you think the EE curriculum is any different, say, between Berkeley and Florida? [It’s not.] The only difference is the students at Berkeley will be a bit more academically competitive, and you will have to work quite a bit harder to get that A. But the actual curriculum? Really no different.
And the difference between Purdue and Florida? Meh… not so different that you should go into significant debt.
