The only book I referred to was Head First Servlets & JSP. I borrowed the book from my company library and studied for 5 weeks.
As you might be aware this new version - SCWCD 1.4 is relatively new and you don't find many free mock exams available on the net.
I tried some on 1.3 on javaranch.com/j2eecertificate.com.
For 1.4 if you make a search on google, you'll get whizlabs.com and others which offer commercial exams. You can go to them and download the trial version which contains 15-20 Qns.
After all these, once you feel you are battle-ready, take the final mock exam on the book (HFS&JSPs). As the authors claim, it IS tougher than the real exam. I could manage only little above 80% with that.
Congrats prasanna. That is a very good score. I am also preparing for this usinf HFS and JSP. Did U go thru the API's at all?. Did U have any prior experience in servlets and JSP?. This info will help me get a better idea for my preparation.
