Michael,
You will find the answers to all these questions in the archives of the forum.You may start searching with "LONG POST" with my user name to start with.
If you still have any queries please do let us know and we would be glad to address the same.

You misunderstand. The correct answers ARE posted here(marked by asterisks). In this post I combined the information I gained from your LONG post with information from study/trial-and-error to get the answers for 54 questions from the ICE exam. I am able to get 100% on the ICE exam almost always now. I didn't have a question; I was just looking to help people out.

Thanks for you hard work and your generosity and sharing it with the community. The only missing piece of the puzzle is some questionns refer to diagrams. If we could get hold of the diagrams.

Hi,
I am not sure if it is ILLEGAL to post the answers like this since IBM is not releasing the answers for the test.
I would ask the mderator to verify this.

Faisal,
There is no problem in discussing the IBM pre-assessment test questions.They are infact meant to enhance our knowledge on the subject.So please feel free to discuss the same here.
However, posting any real test questions here would be against the policies of Javaranch.
Thanks,
Sandeep
Michael,
Am sorry for the misunderstanding on my behalf.
Thank you very much for the excellent work done to help Javaranchers.You may also consider the advise by Sanjay (on including the links of diagrams) to make the post more complete (or may be you may just post a link to the previous posts in the forum which contains the links.)
Thanks once again for your efforts

I will track down the URLs for the diagrams and add them to this POST. This might take me a bit. What I did for my own studying purposes was to cut and paste the 54 questions (and their associated diagrams) into a MSWord (office 97) document. I don't know how/if I can post the attachment to this site, but if any of you want the Word document,I would be happy to e-mail it to you. Just let me know by e-mail (michael_mcelwee@hotmail.com)if you want it. Thanks.
