I think you are referring to the concepts used by PowerScore (The PowerScore LSAT Reading Comprehension Bible). Since 7Sage does not use those concepts, I think it's better for you to ask on PowerScore boards.
@jkatz1488 nah, i bought all the available PTs and just studied by taking PTs and reviewing the ones I got wrong. I used the free 7sage stuff, powergames LG Bible, and a version of blind review to improve, but that was about it.
