Hi all,

A colleague sent me this as a possible solution.

"one answer to your question is to use the Gradebook to determine Course Completion, and use a Gradebook calculation to work out a total course grade. 

Seminars report a Grade value of 0 = no show, 50% partially attended, and 100% full attended. Via Grade Calculations you can construct Excel like formulas such as;

• max([[item1]], [[item2]]...): Returns the maximum value in a list of arguments.
  

Which is useful if completing any activity can successfully complete the course - but is the same as the All/Any option.

These calculations can be nested so you could have must get a grade of X in a set of activities, and then max[of the sub-set of activities that you need to have completed].

There is way more information at:  https://docs.moodle.org/39/en/Grade_calculations"
