Hi everybody!

Today I heard that I passed for the SCJD exam. My score is as follows:

The maximum possible score is 400; the minimum to pass is 320.
General Considerations (maximum = 100): 99
Documentation (maximum = 70): 70
O-O Design (maximum = 30): 21
GUI (maximum = 40): 31
Locking (maximum = 80): 44
Data store (maximum = 40): 40
Network server (maximum = 40): 40
Total: 400 365

A month after my submission I heard I got an auto-failure. I have described how I appealed (I will update it in a minute) in the following thread. Eventually I passed without having to resubmit.

Automatically Failed because of 48 hours rule

I seem to have missed points in O-O Design, the GUI and Locking (and 1 in General Considerations).
Regarding O-O, it was my first time to implement a Business Delegate, and I used a 3-tier solution (split up DB and server), but maybe my way of splitting up the DB and Server was not so good.
Regarding my locking mechanism, it was very simple. My Record classes contained a private 'locked' flag which was set or cleared through a setLock(boolean) method, which used notify and wait, and was called before and after updating fields.
I thought my locking mechanism could be very simple as I made the methods that I did not needed (create, delete, etc.) unsupported operations (I seem not to have gotten deductions for that and it made things much easier).
Regarding the GUI, the only thing I also minded was that when you maximize the window, the criteria fields resized and became huge. I preferred huge text fields over huge buttons or a lot of whitespace, but maybe there are better solutions. Or I just missed something else they expected.

From an initial Automatic Failure to 91% with (almost) no deductions in General Considerations, I do not feel that the accessor might have given me a lower score on purpose because he did not like to admit his mistake (it took a few mails until he was convinced). I am therefore quite happy with this score.
Of course I'd be even happier if I'd get an apology from Sun or my accessor for giving me an auto-failure wrongly and not setting it right after my first appeal.

I joined this group in my last months of developing. I was happy to join so late, as I had already thought about most design decisions myself and although some messages here have influenced my choices, I do feel I did it all by myself.

Thank you to everybody participating in this list.
Regards,
Dies

Congratulations you, but I guess that you have a wrong about your score.

99 + 70 + 21 + 31 + 44 + 40 + 40 = 345

345 / 400 = 86%

Thanks everybody!

Zhong was right, my calculation of the total is wrong:
it's 345, not 365, so it's 86%, just to set it straight.

I'm now working on Oracle (DBA). I already bought the books. It's a lot to study so it'll take me a while.

Good luck everyone with your exams!
Regards,
Dies
