This topic is for NUPOC, which is an officer program. That said, yes you have a chance. I wouldn't sweat getting another job right now, because if you screen nuke, you are going to be a nuke. Don't worry about that. However if you don't make the cut on the exams, then you will have to choose another job. Again, don't worry about them pulling a switcharoo on you. Just keeps us posted and we can help you through the process, even if you don't get nuke. Just focus on the exams for now and don't sweat the other stuff.
