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.
  
  
• 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.

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!
