What goes on in the different weeks of BMT

I always wanted to know what my H was doing and learning. A lady showed me this link and I followed it all the time.

H did say that there was a lot more "down" time than he thought there would be. He said it could still easily be a 6 week course and they could still learn everything they do now. I've heard rumors that they are thinking of making it 6.5 weeks again instead of 8.5.
