I passed with a good score. I studied alot with Kathy's book and ran the test simulator. I was able to finish the test, but no able to finish checking all the answers. I did all the fact/knowledge questions first. SOmetimes you can look at a code snippet pretty fast and get the answer. I left exhibits with looping, memory management, and thread problems last. Make sure that you study and study your threads. You can't study them enough, even if you have written threaded applications in Java. Be very careful with the wording of the questions and pay attention to when things happen. If you want to get a very high score use other simulators. I noticed that the test simulator I used seemed to focus on the same type of questions, was not random enough. I bought the book on Jan 16, 2004. Read it through 2 times and did the problems and test examples. Wrote up index cards. I have developed java swing applications (with threads) and back end j2ee applications for the past 3 years. If you get very high scores with the simulator from the book you will additional work to do to get that extra 10-15% on your score. The good thing about the simulator is that it helps pratice to do things fast. Don't count it out.
