Exam 70-315

Question

Hi I am preparing for Exam 70-315 : Developing Web application using Visual C# and Visual studio. I have experience of working in C# and visual studio. I need to know generally how long does it take to prepare for this exam (for a newbie with programming experience)? Besides ADO, security, testing and debugging what are the topics that are emphasized in this exam ? Do they ask about XML and web service in this exam? Are there any questions related to serialization and parsing data? Where can I find syllabus for this exam ? Which are the best guide to study Security, testing and debugging part ? I appreciate all your help. Thanks C_sharpkid.
