I completed DP1 in ACISS in the summer of 2018. All of my weekends were free except one. However the didn't allow us to travel home each weekend. Depending upon the behavior of the class, and at the course staff discretions, weekend leave passes (i.e. leave away from base) was either granted or denied. However I do a lot of remote work civi side so that allowed me to catch up. Hope this helps.
