I am not sure how accurate information about the spaces left is. With all the respect to the person who shared this info I believe that rumors like that should not put people off as OAA has 8 days open for bookings in Dec and thats only for Stage 2.
We dont really know how many batches there are gonna be. They said the first batch will start early March and the last mid-summer.
Competition is high that's true. Good luck to everyone!
