I have cleared the SCWCD exam with 92% today. My sincere thanx go to all the folks in java ranch, Head First Servlet and JSP authors(truly this is an amazing book), Whizlab and Mikalai Zaikin.
I took most of the mock exams available online and also purchased the Whizlab testing kit. The reason I bought this kit was some of the free exams are based on the old objectives. Their questions are a little bit tougher than the real one, but they do have a nice explanation for each question. I used to get about 80% in all their exams.
For my preparation I read the HFSJ twice and made some notes along the way. I also studied the API's for the classes and interfaces used in the book. I took the HFSJ final mock exam two days before the test and I got around 73%, (+20% still holds). Also read the Study guide by Mikalai Zaikin twice.
Well, regarding the exam, I did well on JSP stuff although I could have done better on the Patterns. Try reading patterns from the Sun website.couple of questions on the exam, the answers given were wrong, but then I picked the best out of worst. Anyways I am happy that I got good score.
