I went to a school that has a Co-op program, which allowed me to work full time while I was in school. We would be in school full time for a quarter and then work full time for a quarter. Totaling 4 different co-ops and 1 year of experience. For 3 of the co-ops I chose to work at 3 different offices that essentially do the same thing and I had basically the same responsibilities etc... Should these be grouped together or should I list everything separately? Any insight is appreciated. I'm being a bit vague on the experience for the sake of anonymity. Thanks!
