You can get many GMAT war stories at numerous GMAT forum sites available.
Every person posts his/her GMAT experience and approach once (s)he is through this test.
So theres nothing special in it.
Here i go.
The debriefing by this person is unique I never read such comprehensive, informative yet funny and humorous posts. I really enjoyed reading this thread.
But this persons (calls himself crash test dummy) has posted this cool story about his GAMT journey. I like his style of writing. His posts are comprehensive and has some humour in it. Also you find some funny posts in the thread; esp. post #3 and one-tight-slap by MOD in post#4. I literally rolled on the floor out of breath. Gasp.
This person put some interesting facts and incidences in his debriefing.
I am sure you ll find it interesting too.
