Yes the assumption unstated is that "as a family" is less pervasive. But ac-A comes in and contradicts this assumption and weakens (perhaps destroys) the argument. Good analysis :-)
I'm just getting out of the curriculum phase, so I've only taken 2. For my diagnostic I used preptest A and I just finished Prep Test J07, but I have PT1-74 so I can do whatever you would like to go over.
So...from PT1 until which PT does it include old/unconventional games? Since I don't have much time to do all games, maybe I just wanna do those unconventional games only from early PTs :(
