Im no expert but heere are my two cents.
Considerations before judgement:
Late AC and Moo is peregrine and void of course at the 29th degree. The situation is out of your hands right now.
You (Mercury) are in your own sign conjunct an angular (4th) house which I interpret as you submitted a very strong application. Aquarius rules education (9th house) and so the school is Saturn in Sag in 6th which isn't the best placement and I don't think there is any essential dignity.
I would be inclined to say no because of all of the considerations before judgement and there are no future aspects, but then again, unless this occurred before moon in Leo then the Moon and Sag trined so it is possible you will get a positive response, they're just taking a while to get back to you.
Very best of luck! I do hope you get in to where you want to. Let us know the outcome.
