wont it be a good idea to make it compulsory to post a snapshot of the un-official report card we get after GMAT.
Many a times we end up asking advices to wrong people just because "THEY SAY" that they have scored 880(

) in GMAT.
Something similar happened with me , someone told me that he used McgrawHill book and it did wonders , its just great.
Without asking anyone else , I started working on this book , and after a week or so , I found the book was crap . At least the book was not as good as the guy mentioned.
So , I decided to take advise from BB and thats when I realized that I had already lost a week working on that book.
I we have some proof (not necessarily public) for the scores , we may be sure that the guy has really improved his verbal from 27 to 40 and its worth talking to him regarding the tricks he used.
Just a thought guys...
