Same here. 4 points lower than both PT 71 and 73 and 6 points lower than PT79. I got severely toasted in the first LR section. And of course the transfer game screwed me hard too.
Though the Eileen Grey passage and the virus game were very challenging, I still got my usual score on PT79 but PT72 is what has really screwed up many people including myself.
I try to visualize in my mind what i'm reading. This is especially helpful for me in RC when I read a passage with unfamiliar subject matter. The Eileen Gray is a good example of me visualizing the work that she did (PT79, #2).
