PGs,

Being a starter, this is one of the issues that I am facing while preparing for RCs. Well, I started with Manhattan RC, however couldn't improve much by navigating the chapters. Alternatively took a top down approach to start solving the passages from OG-12. Not sure which approach should be the optimal one for cracking RCs.
Any suggestions / advice / tips will be highly appreciated.

Hi Guys,
I m preparing for GMAT, Can someone help me in working on the Reading Comprehension questions as they are heating up my brain. It would help me better if someone helps me in giving the Process of Eliminating (POE) options which i think will be easy to solve.
