I just passed SCJP today with 81% not a great score but..
for me,I would not say that .very less time for preparation..no oop exp..etc.I did study a lot and was expecting something around 90%.More than 70% qs were code based.
Help of javaranch can not be described in words. I mean it.JQplus also helped me a lot.Referring to api documentation frequently ,give clear understanding of the classes and its implementations.
Concepts like Threads ,oo principles 'pass by value' and 'pass by reference' should be very very clear as I have found most of codes based on them.
Thanks everybody for your help.
best wishes for preparations and exam
..going to developer forum
