Hello from Romania Today I took my SCWCD and passed with 91% (not quite happy about it).
Preparation : Time : 1 month (around 2-3 hours / day, 3-4 days / week ) Previous experience : yes
Preparation: 1. HFSJ (I've read it 2 times, after that, getting the mock exam of every chapter ) 2. "SCWCD Exam Study Kit Java Web Component Developer Certification" (not finished ) 3. free mock online exams : jiris, j2eecertifcate 4. Specifications : Servlet, JSP, JSTL1.1 5. Mikalai and Frederic notes.
One week before exam I took Mock final HFSJ (knowing the no of good answers) with 82% - so for me "20% rule" was "9% rule". This was maybe the biggest mistake. That was the "peek" of my preparation, after that I got bored about everything related to the exam . Anyway, in the last week I've continued to learn about it.
Regarding the exam : I missed 6 questions: 2 or 3 : lack of knowledge or attention 3 or 4 : I consider the questions not very clear ( especially on Design Patterns questions with multiple answers ) .
