Although I'm not overly pleased with my score, I am still certified. I used the Manning book and exams, and the on-line exams on this site. I'd been clearing 90+ on the mock exams, so was a bit surprised at my score. Some of the questions took me by surprise -- but I'm done with this one!
One more thing, thanks to this wonderful site and all of the ranchers. I've done more reading than posting - but the questions that are brought up by other folks did spark other questions. This is a terrific site for working towards certs!
