I'm in a similar boat. My RN program runs seven straight quarters, including summers (which are 3 weeks shorter than the fall, winter and spring). Despite that, we have to take 12 credits this summer - no choice in the matter. It's going to be hellish, but I figure that if other folks can do it, so can I. I'll be super busy, but sometimes the momentum takes over and everything works out. It will be over with that much faster, too. Good luck to you!
