Today I cleared the test and I want to share my experiences and the material I used
1. Enthuware - Must do all the tests in it
2. Transcender - Very nice interface to study the material and to remember the key concepts (I know it may be a bit costly but it's worthy, believe me, your memory will take you back to this material on some specific questions during the test where they really nailed down on the concept and you will be thankful).
My advice is try to get more than 70% when taking Enthuware tests, if not then go over and over again until you understand 100% all the questions, same thing for Transcender.
Last advice, if you feel that you are more or less prepared for this certification, then don't take it, postpone it and go back to your selected resources material and once you feel super prepared go and take the test...
Have a goal in mind to meet the timing in the test, try to aim 1-2 min per questions, you don't want to miss the last questions, I found them more simple than the ones in the middle and you don't want to miss these questions that can add points to your score and you are more likely to have them right,
I took my test following the below timing plan which I used during my practices so i could control my timing and get used to the pressure and to the mental speed to solve each question,
I was studying for the 90 Q's in 2:30 mins so I made this table to measure how ahead or back I was and believe me that helped me in the test, because it tells you when to push harder to catch up.
I relied exclusively on Gupta's text and the Enthuware exams. Both were extremely worthwhile considering I had no experience with Java beforehand. I highly recommend them.
Your statement of "My advice is try to get more than 70% when taking Enthuware tests, if not then go over and over again until you understand 100% all the questions" is dead on. That practice got me through the real exam!
