@Kumar I have not personally done the course but I know the course creator - Terry Williams - and she is an expert in the area of NS reports and saved searches. The course will take someone 5-8 hours to complete and is well laid out with excellent videos and detailed exercises. Considering the NS reports class is $2,500 and takes 2-3 days, the cost for this course is reasonable. Terry is available to answer questions during the course as well and that is a good benefit of being able to connect with the instructor.
