I know I shouldn't be posting this in this forum but got to post this here to 'thank' every body who took the pain of answering my questions, and who helped me indirectly by posting doubts/queries that forced me to re-visit
EJB fundamentals or theory.
The score I got is 91% but I found this
test more 'testing', in-depth as well as more questions were quite detailed compared to SCJP/SCWCD. May be it is lack of preparation

but wanted to provide my comments/tips(which every body are free to ignore happily

):
HF book + mock exams are sufficient for this test. Again thanks to Kathy & Bert for this book. It is not only good for clearing this exam but explains all the concepts very well. Still not sure what 8 Horseshoe rating on this forum means for this book and why it is lower than other books. I don't know what this 'Horseshoe' unit means

If you don't want to practice much (code wise) then one has to really go through the book very thoroughly. I also glanced through MZ Study Guide. Thanks to Mikalai. That guide is definetely helpful and covers some of the points that are missing from the HF book (unfortunately). But HF book alone is sufficient if you want to aim for 80% something.
The number of correct answers provided (For e.g., Choose two) makes it easy. Concluding on the correct answer by eliminating wrong answers saved me

Good Luck to every body.
Thanks again,
Deep
