Ih...I would put a wisecrack on your puncuation, but I'll be sympathetic.
AMDA is one of the many musical theatre schools out there. If you'd like to check out some more schools, check out the BFA College Thread.
Not only does your acceptance rely on your talent, but unfortunately for you, the way that you are prepared. But, if you show that you're willing to work hard to make up for lost time and show that you have potential and something to offer, then it makes you stand out as an individual. It's not saying that you'll get in, because it's so extremely competitive, I can't put it into words, but you can walk out of that audition knowing you did your best.
Musical theatre is a very blunt field, in my opinion, especially when you're starting out. If someone sees the potential to train you, then they might see the potential in you that you might have a future in this career. If not, you can either A) Accept that fact and go into another field or B) deny the fact and continue to go out for auditions, hoping that your talent will nab the attention of some agent or casting director.
Hoped that helped and best of luck.
