Q: Is there anything special that I need to remember to obtain good score?
A: Many people read on XML, XSLT, Schemas, etc. but they forget to also read up on XSL FO, XLink and XPointer, DOM Level 3, DTD, etc. So, remember to brush-up on these topics as well, in case a question pops up on these subjects. Also, be prepared to answer any B2B scenario questions, read and answer lengthy problem/scenario questions (but mostly with a simple answer :) ), and practice enough with XSLT, XPath and Schema syntax. And finally, (most importantly) make sure that you understand the role of each specification in XML applications.
