My Experience with Whizlabs

[Chris Judd]

I wanted to report on my experience with the Whizlabs SCJP 5.0 mock exams. I have found errors in the answers to the questions on the drag and drop portion of the mock exam. I've submitted these errors to the company and requested a refund b/c I have lost confidence in the mock exams.

I think this is the first time they are doing the drag and drop with the SCJP 5.0 and some kinks need to be ironed out.

I'm using WhizLabs also and haven't experienced any problems. Mostly, when I revise, I copy the code and compile and run it, so far I haven't seen anything strange.

Would you mind sharing the faulty questions you've found in this thread? Probably a lot of people are using Whizlabs...

Thank you in advance

Here are three examples:

TestName: DIAGNOSTIC, Q No. 72, Q Id. 1017

I do not understand why DateFormat.LONG is the only answer that is acceptable here. According to my testing, DateFormat.MEDIUM could also be use.

TestName: DIAGNOSTIC, Q No. 53, Q Id. 1012

I do not understand why the answer to this question has to be:

if(s!=null && s.length()>0)

Why could it not be

if(s!=null && s.length()==0)

TestName: DIAGNOSTIC, Q No. 19, Q Id. 1006

interface IFace{}
class CFace implements IFace{}
class Base{}
class DFace extends CFace{}
public class ObRef extends Base{
public static void main(String[] args) {
ObRef ob = new ObRef();
Base b = new Base();
Object o1 = new Object();
IFace i2 = new CFace();
o1 = new ObRef();
ob = (ObRef)o1;
o1 = i2;
b = ob;
b = b;
}
}

I concur, I'm running on Vista and pulled their product down. No where on their site did it say that they were having problems with Vista. So I get a runtime exception so I can't use their exam. The guy did offer me a refund, but I'll deal with that after my exam tomorrow.

I've actualy found a few Whizlabs items that are different from the K&B Book/Objectives. I think the Whizlabs though overall is a good product. I think the questions "seem" more realistic to what the test is like.

I took suns "sample" questions (the 10 free ones) for the SCJP and found them closely matching whizlabs in content and type. In contrast I found the MasterExam questions were just insane. While I'll agree that you need difficulty in questions in order to better prepare you should also work to build your confidence. Whizlabs I believe does that with a good mix of questions.

Here is what errors I've found. I've not seen updates to any of these yet but I'd like to have the software updated to reflect actual exam questions/content.

Whizlabs SCJP 5.0 Exam Simulator (TestName: BOOKMARK, Q No. 66, Q Id. 169)The question should probably indicate which line of code independently inserted. Since both correct answers for this can not be inserted at the same time.

Whizlabs SCJP 5.0 Exam Simulator (TestName: Random, Q No. 6, Q Id. 177)This question refers to listFiles(); That method is not a "Key Method" for study on the Exam per the K&B Book Table 6-1 p.436

Whizlabs SCJP 5.0 Exam Simulator (TestName: Random, Q No. 7, Q Id. 1069)Per p.457 in K&B Book DataInputStream and DataOutputStream are NOT on the exam. The objectives of the exam indicate it but are in error on the objective list.
