At the Class Reports level, you can drill down and see more detailed performance information for all classes combined or within a selected class. If you are teaching more than one topic, you can choose to view information based on all the lab-topics/products your students have been using or by a specific lab-topic/product. This report gives you the ability to see how one class is doing compared to another or how well a certain lab-topic is being received compared to other lab-topics you are teaching.
