I studied the Mughal book, did the exams in the Sierra book the weekend before, and did all of the mock exams I could find on the web. I felt pretty comfortable with about 80% of the questions and took educated guesses on the other 20%. I was shocked when I got a perfect score.
impressed! Keep going with high score as SCWCD, SCJD... I got 91% in SCJP, and last Thursday only got 82% in SCWCD, I felt a little for my SCWCD score, but I don't wanna test it again just for the high score. I'm preparing SCBCD now, trying to go above 90%.
