I am preparing for SCJP 1.6, I want to take more and more mock exams. I have seen the forum FAQ, is there any other source for it ( free ones ). or do I need to buy it only?
Had you tried ExamLab ?
you can try certpal. it is good. also you can google it for more. or you can also buy practice book by kathy seirra and practice questions from it. also try whizlab exam simulator. i think that will make you have lots of questions in your arsenal.
