A few questions:
1. Are you in pre-nursing or nursing school
? If you're pre-nursing, have you been accepted into a program?
2. What do you mean by 7 years to graduate? You'll have been in school for 7 years by the time you're done or you'll be in school another 7 years? ROTC works within a traditional timeframe--4 years of school to get your bachelor's, take the NCLEX, commission and off you go.
A few statements:
1. If you're a 4th semester nursing student
, you'll be going to LDAC, not LTC. LDAC is a mandatory course attended between your junior and senior years. LTC is typically attended between sophomore and junior years and is not mandatory.
2. If you want to attend Army PT via ROTC, you should contact the ROTC at your school. We had folks PT with us frequently just to get their feet wet.
3. If you graduate college, pass the boards and are accepted into the military, your contract should stipulate that you'll serve as an RN. However, if you fail college or do not pass the NCLEX, you get a finite number of retakes (I think 2) and then the military can do with you what they will.
4. Disrespect is universal, and just because you're entering the military does not mean that everyone will respect you. Civilians are somewhat untouchable because 1) the unions are powerful and 2) they exist in the system, but they follow a different chain of command than the military. I've know a few civilians who are incredibly disrespectful. They could probably have gotten away with murder. The nice thing is, the military is a family. This tends to catch up to civilians who try to abuse their position and take advantage of soldiers.
Personally, I didn't end up completing ROTC. I did LTC, got my waivers done and did ROTC for a semester before I realized that I couldn't feasibly do both ROTC and nursing school. The ROTC at my school was a satellite program, so I had ROTC labs and nursing clinicals overlapping. The requirements between the two were conflicting and would've been nearly impossible to fulfill. I direct commissioned after college, though from what I've heard, the Army requires 2 years of prior experience nowadays to even apply for a direct commission.
Due to the drawdown, you probably won't end up on active duty as those of us currently on active duty are facing cuts. If you do ROTC, you'll likely be placed in the reserves.
