Here’s a frequently asked question. Why are my users sometimes getting “None” as grade/result on a quiz?

The answer is that None is shown when no grade/result matching the points or percentage achieved is found. This is always the reason, no exceptions.

So please check your grades. They must cover the whole possible range of:

a) points, if you are calculating grades by points (this is the default option)

b) percentage, if you have selected “Calculate grades by % correct answers instead of points collected”. For versions older than 4.2.5 please make sure that your percentage based grades overlap so any decimals are covered. For example if grade A is defined as 80% to 100% correct answers, then the lower grade should be defined as (for example) 60% – 80% and NOT to 79%. Versions newer than 4.2.5 will round the percent to whole number so this will not be required.

You can use the variables %%POINTS%% or %%PERCENTAGE%% on the final screen to help you figure out what is achieved by the user and why they are not getting any grade.

Please also don’t confuse category grades with global grades.
