Java Certification (1Z0-815) Topic-wise Tests

Are you ready to pass 1Z0-815 exam and prove your competency to recruiters and employers alike?

NOTE: Effective 1st October 2020, Oracle had retired 1Z0-815 and 1Z0-816 exams, merged the syllabus of 1Z0-815 and 1Z0-816 and created new exam 1Z0-819. Students may still use 1Z0-815 practice tests to prepare for Java interviews.

The practice test questions have already helped 25 students to pass the 1Z0-815 exam.

Exam Information:

• Exam Code: 1Z0-815

• Duration: 180 minutes

• Questions #: 80 (Multiple Choice / Multiple Select)

• Passing score: 63% 

This course covers all the EXAM topics in orderly fashion, which will help students to assess their preparation for respective topic. This course can be used as a learning aid while preparing for 1Z0-815 certification to test your preparation for each topic while preparing for that topic. 

Topic-wise questions helps in identifying weak areas thus more focus can be given to those specific topics.

Course highlights:
1. All questions are multiple choice or multiple select questions.

2. You have around 2.4 minutes to complete each question which is more than the exam timing. 

3. This practice tests will explain in detail why the right answer is the right answer, in review phase. Understanding the explanation will help in instillation of concepts. Relevant hints and how to approach a question in real examination setting is also provided in explanation.

4. At the end of the practice exam, check your progress and review each question and sort by 1Z0-815 knowledge area, correct answers, wrong answers, skipped questions and questions marked for review.

5. You can take these exams multiple times till concepts are deeply ingrained.

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 (1Z0-815) Exam Simulation", 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!!!
