Well, as I said, a friend of mine who graduated a couple years ago did get a rank boost for having four semesters. He got bumped up to an E3 in the Navy because of it. I did score really high on the ASVAB (I got a 90) so I'm sure my chances are pretty good for completing the college program if it comes to that.But if I can sign on and then do school first, that may be the best option for me.

Having a high ASVAB doesn't do much for you other than give you options for choosing an MOS. Besides the ASVAB score overall doesn't matter, its the composite scores that do. I got an 81, but 2/3 of my composite scores were incredibly high, and the other 1/3 was still high enough that there was technically only like one MOS that I couldn't do.

Also you have to be careful comparing ranks between branches, they all work differently. You can become an E-3 right into basic with some JROTC classes however, I'm not sure how many you are required to have, but it can happen.
