Hello all, I was wondering if anyone has any good advice on how to even begin studying for the QR section. I recently bought a subscription to Chad's, and yes, that was enough to get my feet wet, but I find myself just staring at most of the math destroyer problems without knowing where to even begin in most cases. Is there any other source out there that you all used that helped on the QR (videos, books, etc)? Any help would be greatly appreciated! Thanks!
