If it helps, we've already updated this table in the OCP 21 book to include the prefix "Arrays." before the method name, for greater clarity in each row.
Pass the test? Add your name to the wall, partner. Please read the title/header of table ( written in bold ) to add your name to the appropriate OCP certification table. The first table is Java 21, second table is Java 17, third table is Java 11, fourth table is Java 8, and fifth table is Java 7.

Also, the Enthuware practice tests seem to come pretty close to the actual exam questions. Both in difficulty and topic distribution.HungaryNot really sure yet

Favio TejadaAugust 29, 20221Z0-829 84%I've read the Study Guide by Selikoff & Boyarsky. Along the way I practiced the Enthuware mock tests on a daily basis for about a month. Talking about the exam, I got very few questions on new topics and I'd say it's a bit easier than the 1Z0-819, although I've got a couple of tricky questions on bitwise operators and module migration strategies.BoliviaSpring Certified Professional

Aaqiel BehardienDecember 16, 20211Z0-819 68%Started studying for OCA JP SE 8 November 2020, passed 1Z0-808 in March 2021. Started studying for OCPJP SE 11 beginning of May 2021, passed on December 16, 2021. It was a challenging journey as I had no experiencein the Java language when I started studying at all. Coming from Python it was a different ball game. Many said I needed experience to pass but I had to show myself that I could do it. Using Study guide by Scott Selikoof & Jeanne Boyarsky in combination with Enthuware mock exams, my goal has been achieved.South AfricaOCI Associate

Favio TejadaJuly 30, 20211Z0-819-J 80%Over the course of a year I spent 20-30 min on a daily basis reading a section of the OCP Java SE Programmer II Study guide by Scott Selikoof & Jeanne Boyarsky, then, once I felt comfortable with the concepts exposed in the syllabus, I spent a couple of weeks doing the Enthuware & WhizLab's mock tests (around 24 tests in total). The actual exam did not look that tricky, by the time I cleared up all the questions I still had 30 minutes left. IMHO the Enthuware mock tests should suffice for anyone who does not have the time to read the study books. I would nonetheless recommend getting familiar with the JavaDocs as this exam is mostly about grasping the APIs.BoliviaPIV-SPC

Grant OlsonDecember 3, 20201Z0-819 87%Updated my Java knowledge (formally) for the first time since my first Java certifications about two decades ago. Took the test from home, twice (two attempts). First time, 57%, running out of time with about 5-6 questions left unanswered. It seems that I needed another four weeks to get really confident that I was ready. Used Selikoff and Boyarsky's Complete Study Guide, and Enthuware's practice tests. Also bought Whizlab's practice tests and went through a couple of those. I had a little trouble, especially on the first attempt, with the whiteboard software, so I intended to use a WACOM Intuos tablet to more easily use the whiteboard on the second attempt. The proctor disallowed me from using the tablet, however. My most emphatic recommendation is for Enthuware's practice tests. The Selikoff and Boyarsky book was a worthwhile purchase, as well.USASpring Professional 5.0

Good idea (for my cert results), hopefully I formatted the table correctly!
Just blogged about my experience taking the exam!  https://www.selikoff.net/2024/07/13/passed-scotts-experience-taking-the-java-21-certification-exam-1z0-830/

It was quite different from the previous exams so you really need a study guide tailored to this exam.  Jeanne and I are working on new book that should be out by the end of the year and cover all the topics on the exam.

The 1Z0-830 has to be one of the most challenging certifications exams I've taken.  The length of the questions, number of options, and really long code within some options bordered on ridiculous at time.  While they increased the time from 90 to 120 minutes for the exam, I'd say you are still likely to run out of time.  Some questions are like bad eye exams, where you have to spot a unique reason a particular ~25 line option does not compile.

Taking it remotely was all vastly different from previous exams.  We'll be blogging about that soon, so stay tuned!

While I can't talk about specific questions/content on the exam, feel free to post any questions and I'll try to answer them.  Jeanne and I working to have our book out by the end of the year.  And yes, it will cover all topics on the exam!
The 1Z0-830 Java 21 Exam (and our book) have been officially announced!

Most non-trivial applications use JDBC either directly or indirectly yet it is removed from the objectives while most applications do not use modules but Oracle wants the candidates to have deep knowledge of modules! Same goes for Serialization.



The questions about JDBC were often not practical.  For example, I don't anyone that uses TYPE_SCROLL_INSENSITIVE or CONCUR_UPDATABLE, but they've been on the exam.  They also had questions about Statement, whereas PreparedStatement is often preferred for performance and security reasons.  In short, I was in favor of removing JDBC because of quality issues, but to my surprise, that did not weigh into their decision to remove it.  

In theory, modules is the future of Java, but I rarely see professionals working with them so you're guess is as good as mind.

For serialization, there are some interesting topics there, but I don't know many developers who go deep on serialization (or that use the built-in Java serialization).  A lot of people use Jackson/Gson.
Thanks everyone!  It's nice to be home on the ranch!
As authors, we add/delete/modify many questions between books and update existing questions to include new topics/features.  Sometimes we even change the answer by modifying a line of code to be harder!  

There's also different topics between the two exams.  For example, Java 11 requires you to know how to create custom annotations and use doPrivileged(), while Java 17 does not.  On the other hand there a lot of new topics in Java 17 that you need to study like records and pattern matching.

In short, it's better to use a book for the exam you are studying (and we have both 11 and 17 available).  You can try to mix/match but you may end up missing some key topics.
There’s no points for partial credit so I’m kind of curious where you’re getting the 64.7% number.  For the 1Z0-808 exam, there are 56 questions and passing score is 65%.  If you answer 36 correct, your score is 64.2857% and if you score 37 correct, you’re over 65%.   No rounding needed.

There’s a catch, though.  Oracle may include unscored practice/trial questions on your exam that do not contribute to your score.  We don’t have numbers on how common these are, but we’ve been told they exist.
Correct, starting with Java 11 there is no associate title.  It only takes one exam to get OCP certified.
They are relatively well distributed across objectives (aka you’re not likely to get 20 questions on pattern matching) but there are some caveats. First, there’s a random element at play.  Not everyone gets the same questions or same distribution.  Second, a question might appear to be about one thing, like concurrency, might actually be about something else, like method overwriting.

In other words, yes you need to study everything.  We wrote our books to help you focus on things you need to know for the exam, and often commented when you did not.
Yes, records are on the Java 17 exam.  They are useful anywhere you need to model data, pass data around, or serialize/deserialize to disk or another service.  In earlier versions of Java, you might have used JavaBeans or POJOs.  Record are conceptually equivalent but come with a slew of compiler-implemented methods like getters, meaningful equals/toString, etc.
They used to have drag and drop but after a lot of complaints they removed it.  It is now only multiple choice.  Some questions may have more than one answer, although the exam will tell you how many to pick.
We sometimes write questions that look complicated but aren’t do something simple, like the wrong access modifier.  The exams is done of them kind of questions because you have to read them carefully.
