I got about half of them right - because when I started the cc I focused on going over that whole section. For readingcomp I heard that one doesn't move up much points. So focusing on LG and LR
I wouldn't get wedded to doing it one way or the other, but it would probably be fine. I think I sort of slouched in my chair and propped it up at an angle against the table during one or two of the readingcomp sections and no one complained.
The undisclosed February 2017 readingcomp passage on bees is the one that was most soul crushing for me. I had already done the other bees passage so it rattled me quite a bit.
