I've just passed OCPJP7 (90%) and I would like to share my experience with mock exams I used for preparation.
First of all, for OCAJP7, I used EnthuWare and was happy about it - many questions, basic as well as tricky ones, with clear explanations, links and discussion for each question (sometimes I was sure that there was a mistake, but thanks to the discussion, I found out that that's me where the problem is:-) ). The software itself was easy to use, having the possibility to strikeout answers as it is in the real exam, and to add notes to the answers to easily remember why you chose the wrong answer. I also appreciated the "Leitner mode", where one could go though only unlearned questions (i.e. those which he hasn't answered yet, or answered wrong).
The real exam was easier than the mock tests, but not much.
For OCPJP7, we took a preparation course, where we were given software with mock exams (Whizlabs). The tests were full of terrible english, disgusting UI, old questions (for java 6, which were not correct in java 7) and sometimes wrong answers and explanations, which was the worse. Many times, the code was not formatted and so hard to read.
I was happy to find out that enthuware offers OCPJP7 as well and most of the time used their software. I had the same great experience as with their tests for OCAJP - quite a lot of easy as well as tricky questions with clear explanation. Also it could be seen that they did a lot of work with updating from SCJP6 (unlike whizlabs).
When I compare the price, I cannot believe how this could be happening - $10 for great exams, where I couldn't find anything to complain about, and $70 for something hardly usable and only in despair.
Congratulations, Martina! Great score!!!
