Hi, I finally passed my first Microsoft exam (70-290), I got 838. Now I’m thinking of taking another one, I was wondering what the level of difficulty of each one is. I know I’m supposed to take 6 exams, so i chose what I’m interested in. 70-290 - Managing and Maintaining a Microsoft Windows Server 2003 Environment 70-291 - Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 Network Infrastructure 70-293 - Planning and Maintaining a Microsoft Windows Server 2003 Network Infrastructure 70-294 - Planning, Implementing, and Maintaining a Microsoft Windows Server 2003 AD Infrastructure 70-270 - Installing, Configuring, and Administering Microsoft Windows XP Professional 70-297 - Designing a Microsoft Windows Server 2003 Active Directory and Network Infrastructure 70-298 - Designing Security for a Microsoft Windows Server 2003 Network 70-284 - Implementing and Managing Microsoft Exchange Server 2003 Thanks in advance.
