Just to clarify - you say you were accepted to three schools, but you list six. Assuming you’re looking for help/advice on all six…
@turbo93 and @momrath have offered some very valuable advice and things to think about. Now, here’s my two cents worth:
One point to clear up quickly - it’s not the amount of scholarship dollars that matter, it’s the remaining costs after you subtract out the scholarship that you need to consider. By far and away, one of the most important factors is affordability. Are you, or your family, okay with the attendance costs at all the schools that accepted you? Architecture is not one of the highest paying professions, especially for starting salaries.
As others have said, you have some very attractive, albeit diverse, academic choices to select from. I do always advise candidates to consider what their options are if they decide that architecture is not for them. D2’s BArch class lost 50% of its students in her first year. Do the schools you are considering have realistic choices in majors that you might transfer to? Major universities such as Penn State, Virginia Tech, and Arizona offer multiple choices and options if you change your major. Pratt, which is a very good arts/design school, doesn’t offer too many alternatives if you no longer want to be in the design field.
Your schools literally cross this entire nation. You’ve got northeast, southwest, west coast, east coast and a little dab into the beginnings of the midwest. Have you visited any or all of these schools? How’s the climate, the topography, the surrounding area, where do you think you fit? (Although as @turbo93 alludes to, no matter what school you choose, you’re gonna spend a whole lot of time in studio. ) You will be living at that school for five years.
There’s a certain geographic association with where your school is and where you might be getting a job after graduation. Architecture schools frequently invite professional architects to come to campus to crit or judge projects. Networking with these folks is a significant step on the way to getting a job. And, often arch firms are sending these folks to schools as a recruiting/scouting mission. D2 has been sent back to her alma mater three times in the two years since she graduated to keep an eye on potential new hires. And, of course, the geographically closer the arch firm is to the school, the more likelihood they will send professionals to campus. So bear in mind that where your school is will have a significant impact on where you will likely find (at least for your first job) employment upon graduation.
I’ve got to admit that I’m not that familiar with the RPI program, but D2 looked at, visited, considered, and applied to many of your options. For various and personal reasons, she selected Penn State. She’s currently an Arch II at a firm in Washington DC. She did have three job offers before she graduated.
Good luck!
