7sage sometimes sneaks in a question toward the end of a current lesson that isn't related to the material being taught, but was part of a previous lesson we should have already completed up to this point.

I personally don't mind this because on the LSAT, we're not going to have the luxury of doing the same type of questions consecutively. I find that interjecting questions from previous lessons is not only a stark reminder that we need to be diligent reading the question stem, but also a mental exercise that helps us move from one type of question to the next.
