Keep in mind class dates are not assigned until after the review board. This can take some time depending on your paperwork.
As for some of the cranky buggers on here, just leave em be and ask away. The majority of us don't mind answering.
Classes start every other Monday. The last one was August 29th. That only leaves 3 more classes before 10/11. Class sizes are up and down depending on how many captains are in training too. My class was fairly small and we were all paired with a captain during sim.
