<p>You can switch to Marine Corps Option your sophomore / junior year of college. However, there are some requirements that you must meet before you will be allowed to change. At the University of San Diego NROTC Unit, if you are even remotely thinking about switching from Navy to Marine Corps, you are encouraged to join the drill team and PT with the Marine Options. I’m sure there are more requirements beyond that, but that should give you a little bit of an idea regarding the time commitment.</p>
<p>Make sure if you formally make a request to switch options, that you are 100% sure that you want to be a Marine. There were days that I felt like switching over, but I now know I’m in the right place. </p>
<p>Also, a 271 on the PFT is an excellent score! This fall not one of the incoming Marine Options in my Unit received a score of 270 or higher, and that is not an uncommon precedent. </p>
<p>Good luck with everything.</p>
