I think you need first to figure out what your passion is. Of course you can later change if needed but you have to pick a direction first. I notice that you are considering fields that are worlds-apart:
- Architecture (this thread)
- Education Administration ( http://talk.collegeconfidential.com/graduate-school/2078839-where-can-getting-a-doctorate-in-higher-education-administration-get-me.html#latest )
- Engineering ( http://talk.collegeconfidential.com/engineering-majors/2074431-is-it-too-late-to-change-majors-into-engineering.html#latest )
- Philosophy ( http://talk.collegeconfidential.com/graduate-school/2074076-how-difficult-is-it-to-get-into-a-graduate-program-for-philosophy.html#latest )
- Medical ( http://talk.collegeconfidential.com/california-colleges/2071952-opinion-on-university-of-san-francisco-degree-value.html#latest )
Getting into grad school is not easy; completing it is even more difficult. You need to stay focused.
