Frequently Asked Questions (FAQs)
HOW DO I KNOW WHEN I AM READY FOR THE EXAM?
You can be sure about your exam readiness by consistently getting a good score in those practice exams. Generally, a score of 80% and above in approximately three to five practice exams attempted consecutively will assure you of a similar score in the real exam.
HOW MANY MOCK TESTS SHOULD I ATTEMPT BEFORE THE REAL EXAM?
Ideally, you should attempt at least five mock exams before you attempt the real exam. The more the better!
CAN I START MY EXAM PREPARATION WITH THE PRACTICE EXAMS?
If you are quite comfortable with the Java language features, then yes, you can start your exam preparation with the mock exams. This will also help you to understand the types of questions to expect in the real certification exam.
SHOULD I REALLY BOTHER GETTING CERTIFIED?
Yes, you should, for the simple reason that employers care about the certification of employees. Organizations prefer a certified Java developer over a noncertified Java developer with similar IT skills and experience. The certification can also get you a higher paycheck than uncertified peers with comparable skills.
