Averages for students
Hi to All
I have a FM database for my students results. I wish to calculate their average mark - easy but for the fact that some students have not completed all of the assessments so I needs the average of the assessmenst thay have completed - for some that might be 6 out of ten for others 10 out of ten.
I am not sure how to go about this - I have 10 assessments in total
Any help gratefully received
