I took the SCWCD exam today and passed with 89%....although I was expecting in 90's after seeing questions on the exam. But I guess I made a mess in few questions. 62 of 69 were correct. There was one additional question that I got on exam, but it was not scored.
Also read about patterns from a couple of books, mainly examples...i got a whole lot of questions on patterns than I was expecting.
Another topic you may want to review is RequestURI of HttpServletRequest.
I had scored 62% on HSFJ Mock exam that i took 10 days before my exam. Did not follow any other book, nor did I take any other Mock exams apart form the HFSJ mock exam. I started preparing for exam in February. I read only and only Head First, almost 4-5 times... No specs...no notes.
Thanks to Bryan Basham, Kathy Sierra and Bert Bates. Without this book, I would not have had fun reading for this exam. BTW...the graphics were really cool !! Thanks again to all the authors of HFSJ book. Thanks to this wonderful forum as well.
Javaranch rocks !!!
