My GMAT was over two weeks back. I waited for the official scores to come along with awa before posting.
I have not had a chance to post on this board for more than a month now. I wish to thank BB, Akamai, Stolyar and all other friends who have supported me and many others through their fight with the GMAT.
Experience:
The quant section starts off very easy, then gradually gets tougher. IMO ETS considers a DS question tougher than a PS

since whenever I was sure that I had cracked the PS correctly, the next question was a DS. - Ha ! just joking !
Verbal was tougher than OG. Suggest OG and Kaplan as better bets for preparation.
I would strongly recommend writing awa essays everytime you do a full length test, it helps a lot to get a 6 score since EVERY form asks for this detail.
The full length tests of Princeton are bad. Others tests available on the net are also not upto the mark. 800 score is different, not GMAT style, but good for practice. Kaplan is better but their scoring is not perfect, there is some software bug since even when the answer is correct, (as in their explanation) , the scoring system takes it wrong. Anyway , good practice.
Last month was completely spent with OG.
Take PP's before you plan to assault the OG.
Please feel free to ask for any suggestions and help.
Warm regards
