I'm working as a Java developer for 3 years yet I'm not confident with my technical skills. First, I did not graduate with a computer degree. Second is what they taught in bootcamp is just the basics. Third, I heavily rely on IDEs and the internet so I wasn't able to grasp the full essence of the language. Thus I decided to take the exam. I have a number of Java references and I tend to be overwhelmed with a lot of materials so I researched on the best reviewers for the exam. I decided to focus on three reviewers. (1) OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide (2) OCA / OCP Java SE 8 Programmer Practice Tests both by Jeanne Boyarsky, Scott Selikoff; (3) Enthuware mock tests.
The Study Guide is great though I had a problem in the organization of topics in Chapter 5. I also felt that the reviewer needs more topics about wrapper classes, casting primitives (narrowing and widening conversions) and casting objects. Overall the reviewer is amazing!!!
My plan is to finish the Study Guide on my first month of review and focus on Practice Tests and Enthuware mock tests in the 2nd month.
The game changer for me are the Enthuware mock tests. It simulates the real exam! Some questions are even similar. I passed all Enthuware tests but with unsatisfying scores ranging from 65% to 70% mostly because I am careless and did not review the questions after submitting. It's a bit draining answering these questions so I decided to just study why I did not answer the questions correctly. I took the mock tests multiple times. I see to to it that I understand why my answers are wrong.
I scored 92%. I think I can improve my score if only I'm not holding my pee the whole exam. Haha.
Thank you Jeanne, Scott and the makers of Enthuware mock tests. You are the best!!!
