All topics listed above are divided appropriately in 6 tests. Questions are designed based on real examination questions in terms of pattern and complexity. All Exam topics and sub-topics are covered.Explanation of all the correct answers is also provided for reference and understanding. Relevant hints and how to approach a question in real examination setting is also provided in explanation.Successful completion of all the tests will boost your confidence to attempt Oracle Certified Professional -Java SE 11 examination.More information on detailed curriculum and assumptions to be followed for examination are available on oracle certification page.NOTE: Each practice test of this course contains questions on all the exam topics, similar to what is expected in real exam. But if you prefer to solve topic-wise questions, then enroll in my other course titled "Java Certification - OCP (1Z0-819) Topic-wise Tests [2023]", which contains the same questions arranged in topic-wise manner.
