Hi.. Yesterday I did pass the exam with 81, is not a great score but I'm very proud of, it is a very hard exam and I have a few years without developing in java, so for me is great..
My advise: Follow the objective list for the test, nothing more is there, is not garbage collection, enums, inner classes ( but you should understand how this works ), assertion..
Is there a lot of String, StringBuffer, StringBuilder ( you must learn their methods ), operation ( ++i, i++ ), and so on..
the score to pass is 77, you have 140 minutes to finish the test, I finish with 30 minutes left , and i have some time to review my mark questions.. ohh a good advise... mark all the questions you have doubt about, so you can review them later..
to finish : DO NOT take this test lightly is not SCJA, and you have to study..
I took SCJP 6 Kelly Book, but is not that great for me... but Enthuware it's a very good one.. thanks for the effort.
