Thanks to Head First EJB, (all books from the series are so amazing) javaranch forum, ejbCertificate and EJB Plus. I completed HF EJB twice, then started doing ejbcertificate.com exams. Then reviewed the Mikalai Zaikin notes (mostly environment and security) and did EJB Plus exams. When i had around 88% in EJB Plus, got 82% in HF EJB.
Compared to SCWCD 1.4, this exam was a lot easier, for myself. I studied more, perhaps.
