I am doing mock exams on java beat now. I already did Master exam. All those exams are tough. I am not getting more than 70 on any of them. Is main exam too as tough as these mock exams?
The real exam tests your basic java skills, ability to comprehend complex java code. There are questions where you need to find out potential compilation/runtime failure. But such questions are not unnecessarily difficult. Dont worry about your mock scores. They just toughen you up for the real exam.
