Hi Fred.
The SCEA FAQ and SCEA Links sections have all the required info to start. Naturally, your preparation will vary depending on your experience and/or current knowledge.
I'm guiding my preparation using the Cade/Roberts book, some of the tutorials in the links page, and the EPractize Labs preparation pack.
Of course, this year, I've taken various reads of the
Servlets +
JSP and
EJB Head First books and taken some time to work with most of the technologies tested in the exam.
So, my sugestion is: read the Cade/Roberts book, take some of the mocks, and go deeper into your weaknesses by reading the notes/tutorials available on the internet until you feel ready.
That's all
Best regards
Marx
