I just took the exam - scored 92%.
Exam is not very difficult but questions are reasonably good. One needs fair amount of preparation and good background.
Specifications are very important.
I missed 5 questions in total. Lot of questions on tag libraries.
I missed the question about internal mapping that container does. One question on security is tricky. J2EE Pattern questions were simple.
HFSJ - read thrice.
Specifications - once
JSTL Specification first few chapters - to brush up

Did some mock exams on j2eecertificate and javaranch.
Registered on jdiscuss but could never login so couldnt do mocks there.
Finally a day before exam, i took HFSJ mock exam - got 72%. So i guess +20% rule holds good.
Thanks a lot to all ranchers for discussion questions.
Authors - Kathy Sierra, Bert Bates, Bryan Basham, : Thanks for such a wonderful book. I learnt a lot.
