Should I apply early action or regular decision to UMass Amherst?

<p>I want to major in computer science, I have a 3.06 GPA, 1700 sat, and have done a lot of activities, service, and a couple AP courses including advanced computer science courses. I am not sure if it would help me to apply early action or regular decision and whether or not to apply for my major or undecided to get in.</p>
