Hi Folks,
As I found the several topics discussed by experts like
e-GMAT,GMATPill etc. and questions and/or strategies shared by Awesome GMAT Club heroes like bb/Souvik/whiplash2411 etc. on SC very helpful,I'm trying to help you guys all by putting all of them together in this thread for quick reference.
I think this will not only help all of us who are already in the club(almost everything available-most valuable resources, I believe, in our Club about SC under one thread) but also will be immensely helpful to the new comers.
