Last month I finished my OCEJPAD exam, I gave the correct answer to 62 out of 64 questions. Already I had 4 months working experience in JPA so it take me 35 days for my preparation. I used one text book, one Java related discussion site and one exam simulator for my preparation, all these three were very helpful to me.
Before I go for exam I thought I couldn't attend all the questions in a required time, but its a surprise to me to i answered all the questions but I got only 63 correct answers, anyway I was attend all the questions in a time limit.
