Yesterday i passed the the exam with 86%, i failed 8 questions… actually, i expected more during the exam : it was quite easier than mocks i've done. in ExamLab i scored 43% and 51% in the two diagnostics exam, 38%, 44%, 38% on the the 3 practice exams and 33% on the final exam.
i prepared the exam during 4months by using The Kathy and Bert book, the scjp 6 study guide of Richard F. Raposa and a lot of dumps.
this website also helped me a lot to prepare the exam and also motivated me, i found out i was not the only person to get bad score on examlab, so i didn't give up.
my advices are coding a lot and taking as much as possible all the mocks you could find. during my exam i've got some similar (and identical) questions already saw in some mocks.
ps:sorry for my mistakes, my english is very not good... still learning
