Hi Ranchers,
Thanks to this forum and the information provided here, I cleared SCBCD with 91%

. I would like to thank the entire javaranch community for maintaining this wonderful technical forum.
For those who are currently preparing and interested in knowing the preparation details :
Resources followed :
EJB3.0 in action( very nice book to start with.. contains lots of theory though )
EJB specs ( for a very detailed knowledge on all the topics )
ORielly EJB3.0 ( The exercises in workbook are really excellent resources for practicing the concepts )
MZ's notes ( excellent and a very consolidated material for last week reference before the exam )
Whatever mock exams that I could find online..
Also had a last day look at last minute notes of Raghavendra Balgi
I started with EJB in action, then went through specs, practiced basic concepts ( though not all the cases, scenarios ). Reading the specs took lot of time and not even half of the information made lot of sense in first reading

.
Then browsed through ORielly book, again EJB in action, EJB specs. Tried lots of mock questions and read MZ's notes in the last week.
