NewCollegeParent and jagabiti,
My older son started AROTC fall of 2008, He was originally a Civil Engineering Major. One of the first things they do when they start school is fill out a DD104R form. This form is a plan filled out with the students advisor that shows the classes that they will take to obtain their degree. When my son filled his out for Civil Engineering if was a 4 1/2 year plan. This was submitted back to the ROTC office and approved with full funding with no problem. The only difference is that he would spend one more semester at school and commission in December.
Now, one thing to remember, if your DS/DD decide to change majors at some point, and the new major is a 4 year, they will need to be done if the 4 years required. My son switched to History at the end of his freshman year and had to fill out a new 104R to show he would graduate in four years.
Jagabiti,
I am surprised they told your son not to schedule classes on a Friday, my son has always had classes on Friday. PT is usually held at 6:00am and done by 7:00am, just makes sure he gives himself enough time to get to the first class. I am really surprised they asked if he would consider changing majors, That really isn't even there place to do that. During his freshman year he will only have one MS class and one MS Lab per week, PT is usually MWF. Did they tell you a reason why not to schedule classes on Friday.
