Today morning i cleared the exam with 72%. My most of the prepartion was web based as follows:- DTD's - Skonnard, XML in Nutshell Schema - Roger Costello PPT (Very good) and some reference from W3C Primer. XSL - Roger Costello PPT, Skonnard http://www.dpawson.co.uk/xsl/sect2/nono.html#d1362e34 FO - http://cafeconleche.org/books/bible2/chapters/ch18.html DOM & SAX - Skonnard. Mug up the UML diagrams given in Skonnard, as u need to know API's; W3C primer for DOM (It is also good). XPath, XLinks, XBase - Skonnard SOAP, WSDL, UDDI - W3C schools. XLinks - http://www.ibiblio.org/xml/slides/xmlsig0899/ Mock Exams - JavaRanch gives a good amt. of links + XML@Whizlabs I would say no mock exams come near to the real exams. The one provided by IBM is good. I scored 73% in that same to what i scored today. Whizlabs very good for scenario based questions and many other things (gives good explanation also) but still i fell it lacked somewhere when compared with real exam.
