I am a LT Commander 11 now. I thought you did your 10 grades and your promoted. At least that is what it did before when I was a LT. It says grade complete but still need to spend so many points. I have no more skill points to upgrade myself or crew. So does that mean simply I need more missions for more skill points?? I am pretty far along in the missions and even getting some mark V stuff that I cant use yet.
