My DS does not graduate until December 2015, as he needs an extra semester (engineering major.) As such he will be a semester behind his fellow MS 4's and will hang around as a MS 4.5 for a semester. I don't have a clue how the OML/Active vs. Reserve/Branching works for cadets like him. I assume they have a separate list or process for them? I certainly hope they don't just get what's left over from the May graduates...
