With 2 admirals backing her up, plus her Borg "knowledge", she might have been able to skip a bit, if not all of the Academy.
A full stint is usually 4 years, but we know of many instances where people got field commissions early or were able to finish sooner.
Examples are Not who ended the show as a Lieutenant less than 4 years after entering the academy and Alternate Kirk who finished his Academy run regularly in just 3 years (but was almost immediately granted Captain rank due to saving the Federation and Earth.
i can easily see Seven putting Kirk to shame in her ability to pass exams and whatnot with flying colors in record time.
She definitely would have been fast tracked to command and repeated her excellency at every turn.
The part that would be challenging for her is the social component, but she caught up on that during the last 20 years at least a little.
Shaw is denying her Borg Designation.
We are talking about Shaw taking her name away, not the Borg.
I think he should have or at least let her know that shes a fucking dolt to keep her Borg name while surrounded by Borg victims.
if that is Shaw’s view he is utterly failing to grasp that every xB is as much of not more a victim of the Collective than anyone merely being killed by them.
But as a by the book boring career officer who does not do the exciting things he mocks Picard and Riker for, he never was possessed, body switched, salamander de-evolved not assimilated, so would not know.
Hell, he probably never even time traveled or got a Q visit before.
How he is not captain of a Cali-class is beyond me. XD
