The things that the other replies have said are very true. Make sure the school has a good program in engineering. Make sure you are comfortable on the campus -- for example, I was dead-set on going to UofM for engineering. I went up there for a visit, and I couldn't deal with its size. That was something I never expected to have a problem with. The note about classes being common your first couple of years is also very true. I was torn between the same two degrees you are, and I may still decide to add on the other prior to finishing school.
The other thing that's become increasingly more important, especially in the engineering field, was mentioned indirectly before -- you need to have practical experience. I know we get some from work in FIRST, but when you compare your work in FIRST with, say, work at General Motors or NASA, they're really two different worlds. My school, though it is unique, requires 2 years of real-world experience in order to graduate. However, they know that the experience you gain from that, can only help in your career.
Good luck!!
