Hi,
Whilst i didn't actually attend this course (a colleague of mine did) i did go through the course material. I found it very useful because at the time i was just starting out with reporting services. It built up a good working knowledge of reporting services for people that went in knowing nothing or very little. Once i'd finished the course i found i could create all sorts of reports with reasonable ease. The rest just comes with practice. Link to the course:
I notice that they also do a 2008 course now.
Thanks,
Simon
