Congratulations! As far as getting hired after graduation, if you want to work within the CHS system, you won't have a problem getting hired. Most of us had jobs lined up (including hard to get into departments like ED, STICU, MICU, NICU, L & D, peds, etc) a couple of months before graduation.
No, you can't skip that 3rd semester, unfortunately, even if you already have all the other classes done. I already had my CNA so I took micro and got it out of the way. If you don't have any other needed classes, you basically have to sit out that semester. It has to do with the timing of the schedule for admissions, etc.
