OCP Java SE 17 passed

[valerio cesolani]

Hello everybody,
I'm proud to share with you my happiness and relief to have just obtained my certification with a score of 80%.
My last Java certification dated back to 2020 and was OCA Java 8.
Getting this was quite tougher and required many hours of preparation started last June.
I had to take the test three(sic!) times because first two attempts taken at home were disconnected before I had the chance to complete.
Oracle awarded me another try but with the suggestion to take it at another place where connection was more stable.
So this morning I went to my company's office where I had booked a meeting room and attempted from there.
Fortunately this time all went well and I could achieve my certification!
To prepare for the exam I used both Boyarsky-Selikoff and Mughal-Strelnikov textbooks plus mock tests by Enthuware.
I was not that brilliant with mocks, often staying behind required 68%, but I felt that many errors were due to lack of concentration which I was quite sure to show during real tests, and also I have to say they somehow look even harder than the real thing!
So my suggestion is to take the exam as long as you are above 60% consistently with the mocks.
Thanks to this wonderful community which has helped me a lot in order to achieve the result.
Happy testing to all!

Congratulations and thank you for your feedback!
It is good to know that Oracle did not penalize you for technical issues in exam administration.

Hi,
and thank you.
No, I did not get any DST related question, neither on any formatting topic and only one, but very easy, on modules.
I did get nevertheless the silly question concerning bynary search on an unsorted collection where "undetermined" was not an option and I just picked one by heart!

This is a well-known error, which even Oracle is aware of but opted not to fix:

What's the "answer" / recommendation in that scenario then if undefined isn't an answer? Thanks

The recommendation is to pick the best (although incorrect) option.

A 100% wrong answer will be counted if you do not select any option.

If you select ANY option -- 25% success (and maybe 33% in case you can cross out a wrong choice)

Understood, will bear that in mind for my re-take. Thanks!
