I passed SCJP6 today with 86% . thanks javaranchers, it is lucky to have such a great place for java learners; thanks Kathy and Bert for their great book. tried several free mock exams, great thanks to Devaka, his mock exams(1.5) in Examlab is the best to simulated the test enviroment (I scored between 60-70% for 3 pratice exams) . As to the exam, I think it is more difficult than my previous imagination ( I got 75% in Declarations, 70% in OO Concepts, and 81% in Fundamentals, felt bad to lose lots of points in easier section): about 8 "drag and drop" questions, and there is even one question regarding thread need to choose all the correct answers applies(without specify how many correct answers). the first two are "drag and drop" questions, and that really frustrated me. Anyway, pass is not so difficulty, but excellent score need good preparation and lots of practice. good luck to all Java Certification preparers.
