Hi everyone.
I am writing my OCA Java SE 8 certification next week (2017/08/31) . I am very nervous and i not sure of whether Ill pass or not.
I have answered questions from the Enthuware Question Bank and these were my result:

Foundation Test - 78%
Test 1 - 70%
Test 2 - 66%
Test 3 - 79%
Test 4 - 74%
Test 5 - 74%
Test 6 - 85%

As for OCA/OCP Java SE 7 Programmer I & II Study Guide”, Kathy Sierra and Bert Bates, Self Test:

Chapter 1 - 83%          
Chapter 2 - 85%          
Chapter 3 - 61%          
Chapter 4 - 62%

Welcome to the Ranch

I shall move you to our exams fora.

Please tell us which questions you got wrong and why. Start with not more than five and let us see what you have done.

Welcome to CodeRanch. I'm glad you are here.

It does look like are you ready as you seem to be in line with:

https://coderanch.com/t/680805/certification/Passed-OCAJP

https://coderanch.com/t/683117/certification/Passed-OCA

Along with other people on this site who have done about the same on the Enthuware tests.
Most people would say that the Enthuware tests are more difficult then the actual exam and you did rather well on the Enthuware tests.

A few things to remember:

You should be given something to write with and something to write on.

Time management is something that many people struggle with (including me) when it comes to answering the questions.

The test is a difficult test and some times some people do not do as well as they want to. So do not beat yourself up if this happens to you.

You can actually, right now log in to the correct Oracle/PearsonVue portal and see your test results.  It will say that you have not taken it, but you can do this now so you don't have to wait and figure this out after the test. This does not speed up the process of marking the tests in any way.

Give yourself a good night's sleep before the test.

Give yourself plenty of time to get to the testing center. You should show up at least 20 minutes (if not more) before the test.

Good luck to you, and I hope it goes well.

Thank you. Id be more than happy

Here is a sample code i don't understand :

public class Test {

static int count = 0;
int i = 0;

public void changeCount() {
while (i < 5) {
i++;
count++;
}
}
public static void main(String[] args) {
Test check1 = new Test();
Test check2 = new Test();
check1.changeCount();
check2.changeCount();
System.out.println(check1.count + " " + check2.count);
}
}
Please explain to me why the answer is 10 10 .
I thought the answer is 8 8, since the while loops checks if i<5. So its true only if i<5 therefore count is only incremented 4 times. I understand that the same static variable 'count' is shared among all objects.

I'm very grateful for your advice

When you post code, be sure to UseCodeTags (that's a link).  Here is what your code looks like properly formatted:

public class Test {

	static int count = 0;
	int i = 0;

	public void changeCount() {
		while (i < 5) {
			i++;
			count++;
		}
	}

	public static void main(String[] args) {
		Test check1 = new Test();
		Test check2 = new Test();
		check1.changeCount();
		check2.changeCount();
		System.out.println(check1.count + " " + check2.count);
	}
}

Remember that i starts at zero.  Zero to four is five iterations.

There is one thing in this code you should not do.  Don't access static members from instances.  I know this is sort of the point of the program, but just remember: don't do that!

Oh yes. It's five iterations i.e from 0 to 4. Guess I should pay attention to the code I am given right!
Thanks Knute

Interesting, you used a Java 7 book to prepare for a Java 8 exam?

I did not know that Java 7 and Java 8 were so closely related that one could do this.

I guess, sure as long as one used other material as well.

[Jeanne Boyarsky]

Pete,
There weren't that many new topics added the OCA from Java 7 to 8.  There were a ton for the OCP so the strategy of using a Java 7 book won't work there.

[Pete Letkeman]

I did not know that Jeanne, thanks. And thanks for letting us know about the amount of changes in the OCP exam with regards to 7 and 8.
