this Q 4 USMC reservists going to school, do you need to go to a school that has USMC rotc or no, what r some?

Answer 1

I'm not a Marine or currently a reservist, but I was in the National Guard when I was in school and there was no requirement that I participate in ROTC.

As it happens I did participate in ROTC while a Guardsman.

The USMC doesn't have ROTC at the college level. Naval ROTC commissions both Naval and Marine officers.

By the way I was an Air National Guardsman and participated in Air Force ROTC, but I knew reservists and Guardsmen who earned commissions in other services. You could probably get good specific information from a recruiter.
