I am glad to say that I have finally passed the SCWCD1.4 upgrade exam yesterday with 96%.
Many thanks to the good book HF Servlets & JSP and the mock exam simulator JWebPlus V4, which I won in one of the JDiscuss website promotions last year, I was able to pass the exam easily. My preparation wasn't good and had felt that my weak areas were the new topics EL, JSTL and Simple tags. The day before the exam, I took Kathy's final mock exam and I actually failed, obtained 60% (I believe the pass percentage is 62% )
I retook the same mock exam in the morning again and obtained 90%. Then I walked into the testing centre with some confidence.
thanks to all the good posts by the JDiscuss members and the fellow ranchers here at the ranch
