The differences training starts your 9 months all over again. As far as bidding is concernced, if you are scheduled to finish by the 25th of the month you are allowed to bid for the next momth. I started differences on the 7th of April and was allowed to bid for May. I was lucky, I didn't have to sit a day of reserve on the 70. But now that RJTrash has come over who knows whats going to happen for July....but then again I might be bidding MD.
