Ashutosh,
I wish I could remember all of 74 questions. You have to try IBM pre-Assessment/Sample
Test to get the feeling of what kind of test it is.
Time is very critical for me to answer 74 questions within 90 minutes. I am still not used to those kind of question like "most likely" and "least likely". In fact, most of time, all of the 4 answers are reasonable, they just ask you to pick the best one. I am kind of guy of programmer's thinking, I prefer the JCSP type of Exam, you got exact one answer after you read the code.
All the questions are testing your foundamental/conceptal understanding of XML basics. I got two questions on Xpath that I did not prepare for it.
I will recommand "XML pocket reference book" from Oreilly (no matter which big book you are planning for this Exam), i read through them on the last two days. It is less than 100 pages (pocket size), but it helps me to review what I knew/learned. I only spent less than two weeks on preparing this Exam. It doesn't mean this test is easy, but I have been working on related project in last six months.
Enoc
BTY: the cost for "XML Pocket Reference" only costs for $7-9 from online store.
