Hi - Thanks for the reply.
Since I have started I thought I would learn the basics and learn from OG. I intend to go to Princston once I am finished with OG. I know there is no specific pattern or rule for preparing for gmat and it depends lot on the person, but is my approach to finish with OG not a preferred approach ?
I can not comment on this. OG has all the real exam questions. So if you start with brushing up your basics and then practicing GMAT tricks, it will be easy for you to solve OG.
And if you want to continue doing OG, simply learn this AD BCE tecnique from princeton and solve DS.
Trust me, it will make your life easier. The funda is
