NOTE: If you prefer exam simulation to assess your preparation for the certification exam, then you can enroll in my other course titled "Java Certification : OCP (1Z0-809) Exam Simulation [2024]", which contains the same questions but pattern in Exam Simulation course is similar to real exam.
Disclaimer: These questions are not real examination questions / dumps. These questions are designed based on real exams in terms of pattern and complexity to help you understand the type of expected questions from each exam objective.
Last but not the least, RELAX, and enjoy the tests!!
