How to study for 1Z0-817 OCP Java 11 Certification Upgrade Exam

Collection of books and resources for Oracle Certified Professional Java SE 11 Programmer Certification Upgrade Exam 1Z0-817



Note: Oracle has announced that OCP Java 11 Upgrade Exam 1Z0-817 will be retired on 30th Nov 2021. This means that you can't take this exam after 30th Nov 2021. So, if you are preparing for this exam, better take it as soon as possible.

The 1Z0-817 exam lets you upgrade even your old OCJP Java 6 certification to OCP Java 11. Hopefully, the new upgrade certification (if Oracle releases it for OCP Java 17) will also allow the same.

As of this writing (Aug 2020), there are no books specifically geared just towards OCP Java 11 Certification Upgrade 1Z0-817 Exam but the book by Boyarsky/Selikoff for OCP Java 11 Part 2 1z0-816 exam covers all the topics required for 1z0-817 exam. For the current list of topics required for 1z0-817 exam, check out official exam objectives.

If you don't have the above mentioned book, that's fine. The upgrade 1z0-817 exam is a lot easier than the regular OCP Java 11 Programmer Certification Part 2 1Z-816 exam and you can study for it from existing resources. It covers a small range of topics.
