1) The options presented before you are great. You applied to these schools because they had an impressive blend of factors you were considering such as major, cost, school size, location, student:faculty ratio, rankings, community, athletics, arts, service, alumni network, study abroad program, and residential life (just to name a few). But all of these factors don't have the same value. So choose the top 5 factors.
2) What are the essentials you need today, from the college you expect to grow in as a person? After choosing those top 5 factors from point 1, rank them in order of personal value. How important is it that you end up at a school with a strong sense of community? How critical is the actual rankings? Where do you need to be in order to achieve your personal goals - does location matter?
3) Do you have the option to change your mind and still thrive in this environment? What if after three semesters, you no longer want to major in Architecture, then what? Do you have viable options in this environment to grow and discover other possibilities? Is their room in the curriculum to explore other fields without feeling as though you are wasting money and time?
4) The Money Factor. How content are you and your family with the financial aid package? What would you have to do to make up the difference if there is still a considerable gap? And if there's a considerable gap, discuss with your family a limit on personal loans (federal and private) to avoid being burdened with high interest rates and overwhelming debt after graduation. Especially considering your major and the uncertainty of the job market. These are factors that have to be part of the conversation, when deciding on college.
5) Where do you actually see yourself? After all is said and done, when you close your eyes and imagine yourself in college, where do you see yourself? Which school just fits you? The class sizes, the residential halls, the location, the community, degree programs...some things are non-negotiable for you and this particular university fits the bill. When you've crunched the numbers, weighed your must-haves, what school is left standing? This is the place where you belong.
