Sorry but you have no chance with DC - they only have 2 classes in each year and there are no kids leaving from this years 2 and 3 this year. Even if the odd place did crop up there are over 8 kids on the waiting list ahead of yours

With respect to DESS you have a better chance as there are 4 classes for each year - average wait is about 1-2 years - but they are very fair.
