Hi everyone. I would like to set up my grades for a certain component to automatically select the best 4 marks out of 5 submissions. What is the best way to do this? TIA
 

For example, the students have an opportunity to make a posting each week for 5 weeks, but only their best 4 grades are required to add up to the component marks.

Is there a way to set that up so that it happens automatically, or do I just go in retroactively and make them exempt for their lowest graded posting?
