There are two parts to the grade for a workshop a grade for your submitted assignment and a grade for doing an assessment.
Now lets say there are two people john and ryan. Both john and ryan submit their assignments. John marks ryans work but ryan doesn't mark johns work. Time goes on and the activity ends. John is left with out a mark, but he has done all the requirements!
How does moodle cater for this? Would this just be a thing where you enter a grade manually for that submission? Or would you assign a teacher to grade that submission?
