So today was my big day, taking the SCJP 1.4 exam. And I passed with 81% (50/61) .
My advice is to focus on taking a lot of mock exams. I actually failed about a year ago after just studying a book and taking very few(and too easy) mock exams. This time I used the Whizlab exam simulator and found it very useful. I also used Dan's questions for studying and Marcus Green's mock exams for last day's of preparation. My final score, 81%, was about the same as I had on Marcus 1.4 mock exam and the final exam of Whizlab.
I would like to thank JavaRanch, Marcus Green, Dan and most of all Whizlab for coaching me to this success. Now it's time for 2 week's vacation .
