Going to be attending 25D school. What to expect?

Transferring units back to a 25B, which will become 25D as of 1 OCT. planning to attend the 25D con early 2016. What should I expect when I get to Ft Gordon? Haven't been there since 2006. I have the basics on the class, but interested in life while attending the class? Have to deal with typical 15th Signal BDE nonsense? I have a MacBook Pro, but should I bring a Windows computer instead? I also heard that training is 6 days a week. Is that true? Any info that can be provided would be much appreciated!
