On a similar boat here! I'm taking one this Saturday and my last PT is from like a month ago. I've only taken like 3 PTs in total and my last one was a really good score so I didn't want to discourage myself by taking another and getting lower score…
The default setting for drills is that it pools from older PTs (I think PT 101-130 or something like that) only. When you do PT just do the more recent ones they'll be more indicative of current LSAT trends anyways and they'll be brand new questions…
