OCPJP 6 With 90% and Queries on OCPJWCD 6

[Pratap Raj]

Hi fellas

I cleared my OCPJP certification with 90%...(I was so eager to create account and write this after clearing my xam )

thanks to head first guys for creating awsum book and spl thanks to kathy and members of this blog who really spend time in solving other problems.

well I want to write OCPJWCD 6 Certification (Java Platform, Enterprise Edition 6 JavaServer Pages and Servlet Developer Certified Expert Exam) soon....
so i bought Head First servlets and JSPs by kathy so my queries are like this

1)Is it enough if we study only HFSJ 2nd Ed book and give OCPJWCD 6?
2)OCPJWCD 6 will be same as OCPJWCD 5 or they may change questions as such ?
3)Where can i get free Standard OCPJWCD 6 sample examz (Becoz i am poor i can not afford to buy )
4)Is Head First planning to release HFSJ 3rd Ed in near future ? so when can we xpect ?(I want proper answer )
5)Is there any source that explains OCPJWCD 6 and 5 differences ?
