I entered my first year at a Public Ivy straight out of high school with enough credit hours to qualify as a sophomore -- this without AP credits. I'm taking a full course load (three lower-divs, two upper-divs) and managing high 90s in everything except in Greek, in which I have a 94. By the end of this quarter, I will have junior standing.
I have completed all of my GE requirements and have even chosen to take several foreign language rather than test out of the requirement, just so I can take more courses. I am already halfway to the unit cap. Hence, it simply isn't possible to stay for four years.
Moreover, by the end of this year I will have completed all the prep-level coursework for my major, as well as five classes out of the ten I need for my two minors. I am beginning undergraduate research in the spring and will be able to begin my honors thesis in the fall, when I have senior standing.
Therefore I could very easily graduate in two years. This without overloading on courses but still getting the full bang for my buck, so to speak. I would still be participating in several internships, volunteering and mentoring in the community, and holding several leadership roles in on-campus organizations. I am not trying to rush through college -- I planned efficiently and will be taking classes which interest me, rather than busying myself with expensive intro classes.
My family does not recieve financial assistance and is paying for everything, so I would like to lessen some of the burden on them, particularly as I intend to go to grad school.
The grad school I am interested in has a partnership with a well-regarded law school which would allow me to graduate in two years with my Master's and JD with a significant grant by the time others from my year are finishing up with college.
Tl;dr I can graduate in two years and my advisor looks upon this favorably, shall I do it?
