I can't answer, as I have no experience with eEpractize. My Whizlabs mock scores were +/- 80 %. The Whizlabs final mock is still quite unique.

You made me take look at their website. I was suprised that eEpractize also has mock exams for part II & III.
Is it useful for preparing part II & III?

I would like to hear more about experiences with eEpractize.

I found the Whizlabs mock exams useful for training and estimating if I was ready. I used it during the last one and a half week. However, the real exam appeared to be more difficult. I suggest substract 10% from the Whizlab's result to estimate the real exam's result. The real exam took me also a full two hours intensive text interpretation, while I passed the mock exams in often less than one and a half hour.

A drawback is that Whizlabs is somewhat 'buggy' and some questions seem ambiguous, not always well posed. Also annoying was what I experienced three times in a row at 22:34 GMT+1: I was thrown out the mock exam, and Whizlabs homepage responded during 5 minutes an 'internal server error'. Is this a scheduled unavailability? But this is not a reason for not using Whizlabs.


Two days ago I passed the part I exam.

Regarding the patterns section of the exam: 'Learn the J2EE patterns as if nothing has changed since 2002'. Focus on the patterns' intentions, benefits and forces for using them.
Accurate reading of the 'core J2EE Patterns book' is necessary.

For other sections of the part I exam, it is of course required to know the Java EE 5 very well. This means reading a book on ejb3, the Java EE 5 Tutorial and hands-on experience. The Java EE 6 Tutorial is also useful to learn what was missing in Java EE 5, like an older J2EE Tutorial to learn what Java EE 5 brought us.


It will be a race against the clock for me.
I strongly prefer self-study. Without the ability to learn by self-study, one can't be a good developer or even an architect. There will always be new techniques to know, before any course is available.
By passing an exam, I can show that I know the subject right.

Would it still remain an option to pass the exams (part I, II en III), without doing any course? (even after august)

This would allow me to tell anyone that I passed the required exams. Without having a certificate, but with some documents that state that I passed the exams.

I don't like this. Just got the approvement to do this certification track. Now I have to tell that things changed, which effects reliabilty.


The SCEA study guide [1] states on p. 126, section Core Java EE patterns, that 'Some patterns have become obsolete with new technologies introduced in Java EE 5'.
The guide doen't tell which patterns have become obsolete and what the consequences are for the exam.

My questions:
- Do I have to learn and treat the obsolete patterns as if nothing has changed since 2003, or do I really have to find out what the impact of Java EE 5 on these patterns are.
- When answering the exam's questions, might it happen that I am expected to give an obsolete answer?
- Which patterns have become obsolete (and why)? Is any updated, good and complete source of information available for Java EE 5 core patterns?

The last question is partly answered in Real World Java EE Patterns [2]. For part I preparation this book is not complete enough (assuming that I really have to know what the impact of Java EE 5 is on the core J2EE patterns). I think this book will become more useful for part II and my daily work. Having read the first 150 pages, I like this book so far.
