Hi everyone! I've just become a MCDST on 18th Dec 2006. Just thought of posting this news to share it with everyone here. It's a wonderful Christmas gift I've received this year. The feeling is great! I'm now looking forward to take exam 70-621 when it becomes available in Feb' 07. However, my question is: How can I prepare for exam 70-621 since there aren't any training materials, courseware or Microsoft Press Books released for this particular exam?
