I would rate the exam as medium and the quality of exam has quite a space room for improvement. sometimes the questions are not clear or not really in the scope(in my opinion) and some of the answers are vague. However, there are also have some good questions on testing our understanding of Java Web Services. Personally, i don't like the DnD questions too.
I need to spend quite some time to figure out how to answer the questions.
Overall, it is still a good experience for me to learn and took the exam.
I guess my chances of passing is 50%. Just wish all those who are going to take the exam in this few days All the Best!
