Here is the

**second half of the database**I amassed after

**intensive conflation**from several sources on the net and also from numerous students who appeared for the

**GRE**on and before

**20th Sept 2007**. I have tried to provide answers for as many questions as possible. And due to repeated requests for more

**Quants questions**for the month of

**September 2007**. Henceforth, I have expedited matters a little, trying to present as many questions as possible, yet managing to

**not compromise on quality**. I thank all the people who have been instrumental in producing this

**GRE preparation material**. Hope you

**benefit from this pool of information**. Keep looking for updates.

...............

As of now, I could consolidate only

**problem solving questions**. And you must understand that it is not easy to collect Quantitative Comparison type questions. Not many who have appeared for the GRE were able to recollect the quantities in the two columns. And even if they do, it takes me time to verify them .So

**kindly put up with the delay**. And please remember, do atleast give a cursory reading through

**the previous month's (August 2007)**Quants and Verbal questions Collection. It is important to go through the questions that appeared

**two months prior to your exam date**.

GRE UPDATE- Sept '07 Quants (Part-1)

All the Best.

**Keep Looking For Updates.**

Sincerely,

**Praveen Chandar.**
