I gave the SCJP 6 exam yesterday, and passed with a 93%.
My score sheet said the pass score was 58%
. There were 60 questions to be answered in 3 hours.
For the most part, the questions were quite simple.
I used the Kathy Sierra book and downloaded the mock exam from this site http://www.examlab.tk/
to prepare. The questions in the mock are good and much tougher than the real one, and the GUI is very similar to whats in the real exam.
Just one more thing. The drag and drop answers get reset when you try to review them, so be sure of your answer before you hit Done on them!
