I might recommend turning the BR recommendations off. You can do this under Preferences on your account. If you find yourself second-guessing yourself constantly, it may be better to just use a system of flagging questions you're unsure of and BRing those questions, without a sense of whether you got them right or wrong, and being willing to select the same answer choice.

Hey!

7Sage and LawHub have the same material, so no worries there! The overlap is complete, you've probably just encountered only some of it so far. Comparatives will only be on the more recent tests, as some of the PTs on both sites are from before LSAC added comparative passages.
