Engineering easier then NNPS? Good one. Actually, depends what school you go to. If you go to a top engineering school, guess what sweet pea, the average engineering student will have a 3.8GPA and score in the top 5-10% in the ACT/SAT. Most of the engineering students would sell their grandmother into slavery to get an A in Thermo. Very competitive. Oh, and +30% of the students are foreign with the best and brightest from India/Asia coming over here to do undergrad. They think RR is doing an eigenvalue calc while on the head. The grading system is based on the curve and this will vary depending on what school you attend. Back in the day, the average was 2.7 with the top 2-3 getting A's and the bottom 3-4 finding a new major.
NNPS it will be 2.5 survive. No curve. Basically pass/fail but they keep score so you can bring it up 10 years later and annoy people that don't care. Nuke will be hard for you based on your CC GPA, but if you want to get through it, you will.
I knew a couple of nukes in college. One got smoked out in a semester and transfered to an easier college (graduated comp sci). A couple more I avoided like the plague because they were tools, but I seen them around so they must have been at least passing. I usually dived into the bushes when I seen them coming.
If this was the 1990's, I would say forget engineering and go finance. There has been a glut of engineers for awhile, no reason to go engineering unless you love it. But, I think the tide has changed and engineering will be a better career going forward then finance. It makes a big difference on what school you attend as to how hard it will be. You want an easier path, go to an SEC school and cruise. Personally, with all the opportunities that should arise with Nuke builds, engineering will be a waste if you stay in com nuke and you are looking for ROI. It's mucho mullah, and mucho hard work with no pay. You are looking at 6 years navy, then 4-5 years engineering. Then when you graduate, you are a nub engineer with 0 experience starting out at less then rookie (take home) aux operator.
Basically, my whole e-div got out and to to college. The ones that went to busAdmin did very well. Oh, one did stay in now that I remember. got out a master chief a couple years ago....and two divorces, two spousal abuse convics, and a couple DUI's to round out the ol resume.... 4-oh sailor.
