How to pass Java OCA OCP 11 1Z0-815 Certification Exam

It is has been six months since the new Java 11 OCA/OCP certification 1Z0-815, 1Z0-816, and 1Z0-817 exams have been released. We have been getting questions every day about how to prepare for these exams. We would like to answer them in this article. Before we get into the details, you must know that Oracle has actually scrapped the OCA level certification for Java 11. The steps for passing the OCP Java 11 exam are as follows:

Steps to prepare for OCP Java 11 Part 1 1Z0-815 Certification exam

  • Step 1. Start with OCP Java 11 Part 1 Fundamentals Study Guide by Hanumant Deshmukh ($2.99). Go through each chapter carefully. The book includes coding exercises at the end of every chapter. You should do those exercises as that will help you internalize and retain the concepts for a long time. Another OCP Java 11 book by Jeanne Boyarsky and Scott Selikoff ($76) will also be available in the market soon.

  • Step 2. After you are comfortable with the theory part discussed in the book, you should start with the OCP Java 11 1Z0-815 mock exams ($9.99). Practicing with mocks exams is important because it tells you how well you are prepared for the real exam. Enthuware mock exam suit contains 7 mock exams that reflect the style, toughness, and topics covered by the real exam. Since they closely mimic the real exam, attempt them as if you are sitting the real exam.

    After taking the first mock exam, you should analyze your score. Enthuware mock exams include detailed explanations. Make sure you go through them even for questions that you answered correctly. The detailed progress report will identify the topics in which you are weak. Read those topics from the book again before attempting the next mock test.

  • Step 3. Proceed to the next mock test. Your goal is to increase your score with each test. Enthuware mock exams are a little harder than the real exam and most candidates score 10% higher on the real exam than what they score on the mock exam. So, if you pass a mock test, you will most likely pass the real exam. However, you should aim to get more than 80% on the mock exams.

    You may take the same mock test again but do not rely on the score that you get on subsequent attempt. Score on second attempt is very unreliable because you will inadvertently remember the answers from the previous attempt. We suggest not to retake the test at all because there are enough number of unique tests in Enthuware simulator.

Note that Oracle allows candidates who have passed the OCA Java 8 exam (1Z0-808) to take the OCP Java 11 Part 2 exam (1Z0-816). So, if you don't want to purchase books for the OCP 11 exam, you may take the OCA Java 8 (1Z0-808) exam and then take the OCP Java 11 part 2 exam (1Z0-816) later.

Preparing for OCP Java 11 Part 1 exam using OCAJP 8 resources

Since OCAJP 8 exam has been around for several years now, there are a ton of resources to prepare for the OCA Java 8 exam. If you have access to those resources, you may use them to prepare for the 815 exam. The OCP Java 11 Part 1 exam is similar to the old OCA Java 8 exam in terms of toughness but you should be aware that there are several changes in the exam. You may first read about our detailed experience on the OCP Java 11 Part 1 1Z0-815 exam.

You can use chapters 1 to 19 (except chapter 13 on I/O) of Herbert Schildt's Java: The Complete Reference, Eleventh Edition to prepare for Java 11 part 1 certification exam.
  1. See the comparison of exams objectives for 1Z0-808 and 1Z0-815 first. Make a note of the topics that have been added (most notably Modularization and var declarations) and of the topics that have been removed (most notably the Date/Time API).

  2. Go through a book for the OCA 8 exam such as this or this.

  3. OCP 11 part 1 (1Z0-815) exam is a little more advanced than the OCA 8 (1Z0-808) exam on overriding of methods with respect to generics. So read up on how generics affect the return type in overriding of methods. Try this book for reading up on Generics.

  4. Read about modularization topic from online tutorials. You may also go through Chapters 1 to 6 of this book.

  5. Read about new features of added in Java 9, 10, and 11. You can google them. There are several online articles about them. You need to focus on the following topics:
    1. Modularization
    2. Local variable type inference (var declarations)
    3. New methods in String/StringBuilder
    4. New methods in Arrays class - compare/mismatch
    5. New methods in Collections API (Set.of/List.of)
    6. Functional interfaces - Supplier, Consumer, Function, Predicate

  6. Finally, use Enthuware's 1Z0-815 Mock Exams to see how well you are prepared for the real exam and to plug any holes in your knowledge about the topics that are on the exam. Start with the first Standard mock exam and see how you score. Make sure you go through the explanations (even for the questions you answer correctly) because we include a lot of important tips in the explanations. Read up on the topics on which you scored less from any online resource before taking the next test. Your goal should be to increase your score with each mock test. If you are able to pass any of the standard mock exams in first attempt, you should be good to go for the real exam!
