I just went through the process of evaluating and choosing a college with my son last spring, summer, and fall...he graduated from HS this past May. At any rate, YOU have to make this decision...not your friends, your family, and certainly not the posters on CF.
I would encourage you to visit all the schools you apply to. You should take the formal campus visit which typically entails a meeting with or presentation from the admissions department and a tour of the campus from a current student. If possible, doing this while school is in session is preferable.
Ask lots of questions and get lots of information about:
+ the academic programs (do they have the course of study you want and more importantly do they have other options you have interest in because over 75% or students change majors during college).
+ the academic environment (what are the class sizes; will you have the access to professors that you desire; is there an opportunity for an undergrad to get involved in research, internships, coops, or studying abroad). I personally think this is important because not everyone learns best the same way. Many of the more elite schools strive to have all of their students study abroad.
+ the living arrangements (how many years are you required to live on campus, do they have formal learning communities, and do professors live on campus with the students). Schools have come to understand that where and who you live with has a huge impact on your success rate as a student. Many schools require you to live on campus for 1 or 2 years and an increasing number are trying to do what many of the Ivy League schools have always done...require you to live on campus for your entire 4 years...Vanderbilt, for example, requires this. Many have learning communities where they house certain majors together and may, in fact, have professors living with the students...something pioneered by Jefferson at the University of Virginia that they continue to this day (it is a great honor to live on the Lawn at UVa).
+ the financial arrangements (what scholarship opportunities exist and how do you access those opportunities, what other avenues exist for financing...from loans to work-study, etc.). With many of the more elite schools, you do not have to apply separately for scholarships...all applications are reviewed for scholarships and, if accepted, the scholarship offer comes with the acceptance. Other schools require you to separately apply for scholarships after acceptance.
I would also encourage you to visit the area surrounding the school's campus...some are very rural and some are in very urban settings. This does have some impact on the school.
Ultimately, the visit will give you a "feel" for the school that you cannot get from brochures and you will likely see yourself fitting in or not fitting in. We visited over 20 schools with my son and he ended up applying to 7. He was accepted at 5 of them. I had hoped he would attend ISU but he chose another path that was a better fit for him.
