Thanks to all the people in javaranch......this site really helped to get such scores. I prepared from Khalid aswell as Kathy and Bert's book.Did as many mock exams as I could. Dan's as well as Marcus links were the best of all. Got all my queries solved from the talanted people in this site.......my personal thanks to all of them. Although I had a bit of programming background,it took 4 months for the preparation.Now I'll move on to give the SCWCD exam.
