First of all, congratulations on your offers.
The great thing about getting offers is now you have better people to give you advice. Professionals who have actually heard you sing! Contact the school to see who you can discuss your concerns with…your future teacher or maybe the head of the voice department. They will be in a much better position to give you an opinion on the future of your voice particularly within their program. Your situation is not uncommon nor will being conflicted dampen their enthusiasm for you. So ask them for advice.
If you currently have a private teacher, discuss the situation with her/him too. And if you get other offers, discuss your voice with those teachers too. These are good questions to ask. And you have plenty of time still to ask questions and to listen to the opinions of various teachers and how they would work with you.
