Reports for Coaches

Greetings,

I am looking for a report that averages completion on ALL the tasks assigned to each student per due date.

For instance, if I assigned 4 tasks with 4 questions each, instead of having to look at the report for each of the four tasks and see how much each student completed, then average that by hand, I would like a report that lists student name and completion of the 16 questions asked.

I have almost 200 students assigned tasks on Khan right now, but the grading is very difficult without this report.

Thank you.
