Hey there!
I have been trying to find answers to the same questions you are asking. I am waiting for the information session on the 15th of September to get more questions answered. I am applying for the Fall 2023 ABSN cohort. I can answer with some degree of certainty that their nursing programs only begin in the fall.
As for military affiliations, you should be able to get a residency in VA if your parents have lived there for ~5 years. You might have to submit an Out-of-State tuition waiver. I am in a similar situation my husband is active duty and a resident of VA, but we have resided in many other states in the past 5 years. I should technically qualify for VA residency because he has been paying taxes there. None of my credits have been taken in the state of Virginia either, I am not too worried about them being accepted. For the ABSN they seem to be most worried about having the 1st degree and A&P I & II and Micro completed in the past 5 years.
I could not answer all of your questions but hope that helps.
