Summer clinicals.

So as it were I am a nursing major who is also doing ROTC at my university. I got a semester behind because I just changed to nursing. Anyways, for ROTC I had to get my 104R completed, for those who don't know this is a set up of who the rest of your college years will be, including classes and yeah. Well looking at it I have to take one class this coming summer, the summer of 2014 I have to take summer class called fundamentals of nursing which I am assuming is clinicals, if not please let me know what it is. And then summer of 2015 I am shipped off to boot camp and after I graduate in spring 2016 I am shopped off to military officers school to further my education. Normally this wouldn't be bad but I am also engaged. We were planning on getting married summer2015 but because of boot camp and my MOS, we will have to instead get married this summer or next. Therefore I wonder how hard and time consuming this class/clinical of fundamentals of nursing is going to be because I don't want the marriage to interfere with neither school or the army to the extent where it would hinder me.
