Course modules that contain quizzess, or even a module that is an exam, have 2 tracking mechanisms for reporting. All slides must be viewed to register the check for completion. The quiz must be passed to register the check for passing the module. When the quiz or exam is completed you will see a screen that shows your score and the results. There is a button that says "FINISH" that has to be clicked to display the final slide in the module. You will now see check marks for both completion and passing of the module.
