Thank you guys for helping me out. Especially Christopher, Ankit, Priya, Vijitha

Your timely answers and help cleared many of my problematic areas.
This is how I prepared:
1. I had prior knowledge of
JSP and
Servlets since i worked twice on projects on these tech.
2. Read Head First Servlets and JSP book twice made notes.
3. Worked on Enthuware Papers, Solved one mock exam by Marcus Green.
4. Practiced in real by messing around with things.
For Design
pattern "Peabody Pattern notes" helped me a lot in understanding this concept.
SCWCD paper is all about learning and doing things in practical. This way we can do good in clearing this exam.
All the best for all the future takers of this exam
