Graduate in 3 Years

<p>This is aimed towards the computer science, b.a. people out there.
How possible is it for me to graduate in 3 years rather than 4 with a degree in CS, I am about to end my freshmen year and will have about 73 units (22 units from community college courses, 23 units from AP exams, and 28 units from freshmen year). I am taking 7 units over the summer too. Currently I have satisfied the Math1A and Math 1B prereq's and am doing CS 61A over the summer. I will have completed all my prereq courses over sophomore year and applied into the major. I am thinking if I take upper divs summer 2012, jr year, and summer 2013, I should be able to finish a year early? Only trying to do this because I came into Berkeley with so many units already and it seems like with a little extra effort I should really be able to pull this off. After I would most likely pursue a Masters at Berkeley too.</p>
