I have done the sample questions on http://www.x-nt.org/questions.html.
I think I did not do too well on those questions and the answer sheet for the questions are not complete. I just would like to know how these questions represent the real questions on the exam. Are they comparable? By the way, if you have done the questions, please let me know what you think about the questions, because for some question, I thought they were not state clearly. By all means, I am not criticizing the questions, I still would like to thank the author for posting the questions.
Thank you very much.
ps. What is your opinions about SCEA@Whiz? Is it worth to purchase one to practice?
