Practicing Quants.. Please help!!

[anshulinpc1]

Hi,

First of all thanks so much for helping others to prepare for GMAT. Probably this is most helping site i have ever came across to prepare for GMAT.

Please help me on the following -

I started preparing for GMAT 1 month back. I started with GMATprep test -1 and scored 500, getting almost 50% wrong in both the sections (Didn't work on the essays). After that i started studying from Manhattan GMAT 8 strategy books. I started with Sentence correction and Number properties guides. I am finding it really good. I am on the 8th chapter (Practicing the REAL GMAT Problems) of Number properties book. Manhattan GMAT book most of the time suggests to practice from OG. But i just read one review that says the OG shouldn't be worked on while horning the fundamentals but once you are done with the fundamentals. Could you please suggest if it is right approach to work on the OG while working on Manhattan strategy books? If not then how should i practice?

Thanks,
Anshul
