Just thought I'd mention that I hadn't replied to this, because it looks way too much like comp-sci homework. Not sure whether that's the same reason others haven't replied either. ;)
A hint though to get you started. You can probably use something like... $student: Student(grade != null) from $roster … with a few lines before that to pick out the roster in a similar fashion. To understand it, check out the Drools Expert manual for the "from" operator for working with lists/collections.
