I tried my hand at the http://www.examulator.com/phezam/exam.php free exam(SCJP 5.0). I scored 76%. Is it possible to predict my performace in the real exam with this. If yes how do they relate.
I do not want an exact prediction as I know it is impossible.
I suggest you try the mocks that come along with the SCJP book written by Kathy and Bert. They are close to what you get on the real exam, if not tougher.
