I passed SCBCD 1.3 with 95% on 31st January 08.
Exam was relatively easy compared to what I thought it might be.
I did not like the review of drag and drop questions. If you review a drag and drop based question, then the previous answer is removed and you have to redo everything. Since review phase is usually towards the end of exam, it is bit risky to review those drag and drop questions if one can't finish them on time.
Books I read : Specifications, Head First EJB, and EJB book by Richard Monsoon-Haefel
Begineers to EJB I suggest reading order: EJB book by Richard Monsoon-Haefel, Head First EJB, Specifications

Next journey is to SCBCD 5.0 .
Good luck to all.
