Passed Java 17 professional 1Z0-829 with 88%

Hello, I passed exam with a 88% a few days ago.

For preparation, I've used entuwhare mock exams, and of course, a book OCP Oracle Certified Professional Java SE 17 Developer Study Guide (Scott Selikoff; Jeanne Boyarsky).
I took about 3-4 months on preparation.

I had a 2-3 questions on serialization and deserialization,  you must know which exception may throw read/write methods in this topic. the same worth for modules.
Also, streams (include primitive streams) - you must also study and understand that topic very well... keep an eye on dropWhile and takeWhile stream methods.

Unlike 1Z0-819, I don't have so much questions on loops and post/pre increment/decrement operators.. maybe one question on switch expression, one question on pattern matching, sealed interfaces, resource bundles, basic String methods (immutability) and reference equality and garbage collection.
Related to new in Java 17, i don't have any question about Spliterator, formatting values (compact number format), and no questions on File and Path interface - the only question in this chapter is how to obtain console in Java, of course, correct answer is
Console console = System.console();

Also, as one colleague from here, I had the same question:
public static void main(String[] args) {        var list = Arrays.asList("g1", "g3", "g2");        System.out.print(Collections.binarySearch(list, "g3"));        Collections.sort(list);        System.out.print(Collections.binarySearch(list, "g3"));        Collections.reverse(list);        System.out.print(Collections.binarySearch(list, "g3"));    }

Prior the exam, I've had a problem on pre-exam check. Lockdown secure browser on my computer didn't work until I uninstall avast antivirus, after that, everything was fine. Avast blocked browser and it automatically closed a second after you runs.

In the attachment is my score report.

Regards

Congratulations!
3-4 months was really quick!

Can you compare the questions in Boyarsky-Selikoff's OCP17 Study Guide and also Practice Tests with Enthuware and the real exam?
It will help the rest of us who are preparing for the exam.

Congratulations Please consider adding your name here.

Probably not; the exam doesn't allow candidates to record questions.

You misunderstand. I am asking how he would compare the level of difficulty, the thrust of each - compared to each other, and comparing their closeness to the real exam.

Yes, comparing difficulty would be permissible. Sorry.

Campbell Ritchie wrote:Yes, comparing difficulty would be permissible. Sorry.

It is actually very important for me because I have been scoring only about 50% on Boyarsky's book of practice tests.
I want to know if they are the same level as the real exam, or much harder.
If they are at the same level, then I might as well give up.
But I felt that Boyarsky's tests had a lot of questions that were "cutsie gotchas" - that are worthless for programming in the real world.

Difficulty is like enthuware mock exams.
Questions in the book have a lot of tricky options.. on the real exam, there is not any tricky question, at least in my case.

Also, I forgot to mention that I didn't have any question about nested classes...

Our questions in the study guide are designed to be harder so you are ready for the real exam. (largely because we don't tell you how many questions are correct.) The real exam does have gotchas though. Neither the book or the exam are meant to prepare you for the real world. They are designed to ensure you know Java well.

Thank you - that is very helpful  

Congratulation, can you share us any docs, labs, links so that can help us to prepare for java 17
