Why do you only state Arizona?
You say you have multiple offers from out of state.....What state are you in? (is it worth paying out of state tution? You may be right next door to a VERY program) What are your other offers? While Arizona is a respectable school for tech....there are also others that are held in high esteem? What are your other options?
What level will you be entering into the university? (The first two years are the same EVERYWHERE...why pay more for the LD.......if it is graduate school....you MUST examine the faculty's credentials and record.)
