You need to do some research on this before asking questions about joining MARSOC. First off I'm not in MARSOC, but as far as I know they are taking officers from any MOS as long as your monitor will release you, which can be difficult depending on the need of the Marine Corps. There has been a lot of discussion on this topic already, read through the threads and try to post a question that hasn't already been addressed. Don't start with the typical "I want to be a killer I kick ass at sports, run 200 miles per week, work out 7 times a day, and other crap like that. Look into the Marine Corps reserves, I'm assuming that you are not in the Marine Corps so for all you know you could completely hate being a Marine, yes it does happen. So to answer your "what should I do," question: Join the reserves (so you can do college at the same time), make it through boot camp, complete the School of Infantry and decide if you really want to invest a lot of time and effort into joining MARSOC, because it is not an easy task.
