Today I passed OCPJP 6.0 exam with 98% marks. I would like to thanks the Kathy Sierra and Bert Bates for the amazing book they have written. I would say that book can teach java to anybody. A special thanks to Devaka Cooray whose contribution to my preparation was immense. And lastly to all java ranchers, reading posts here and trying to solve them surely raises your confidence level.
About the exam, it was not at all tough. However some questions were a little tricky. But overall very easy.
