I am so happy of being a Certified Programmer!!! :-)
I think 83% is not bad...I studied for like 2 months (but I already knew Java...) I only used K&B and their mock exams, I also took the Java Ranch Round (156 question twice), and SOME of the mock exams recommended here. I have to say that most of the mock exams are too old (they use deprecated API) and they actually confused me a little bit...so I would suggest to try only recent mock exams (my lowest score was about threads!!!). I also wrote notes for each objective, and I read them just after the 2 minute drill from K&B, 1 hour before the real test.
I took this test to give my resume an additional value, because I just moved to the US (New Jersey) and I am STILL looking for a job...
How can I update my resume to highlight the certification? Should I put a logo? Do I have to do anything but wait for Sun to send me the certification or is there anything I can do, like downloading the logo?
