Hi guys,
I happily completed SCWCD with 91% on 7th June 2010.
I prepared for only four days. The books I used were HSFJ and Manning.
HSJF is just awesome. Though in the beginning, I felt it's a bit too illustrative, later it became really interesting.
I think the best way to prepare is to study the above books thoroughly. And then do lots and lots of mock tests. Getting a feel of the exam and the type of questions will be really helpful.
Definitely go through the Rancher notes
ScwcdLinks page. All of them are tremendously helpful.
Cheers,
Deepak
