I could finish the exam in 80 minutes, that leaves more than one hour

I felt that the exam was easy and at the end I didn't feel like reviewing the marked questions

I just ended the exam.
References: EJB3 by Oreilly, Pro EJB3
Java Persistence API and MZ Notes. All of them were very useful. You can actually do it just with Oreilly book and MZ Notes. I have not referred to
ejb specs.
Mocks: I have just used sun's assessment and sun's ePractice and whiz labs free exam (both contains around 10 questions).
Thanks for the support from Java Ranch.
I am now looking forward to complete the assignment for Part II of
SCEA 5 Beta.
