Hi I took the exam yesterday and passed it. I thought it was very difficult. I used the Dietel How to program in Java Book the Khalid book and the syngress book to study from. I practiced coding with the JAVA programming language third edition. My scores on the mock tests ranged for the twenties on Valentin's to the nineties on Marcus's tests to 100 on Rules Round up. Thanks to everyone at javaranch for helping me pass the exam. You guys are great.
