[LON-CAPA-users] Creative Authoring - number correct

[Jim Maxka]

Hi Mark -- I have some examples of this kind of question, where I 
generate random plugs for placeholders in the optionresponse question.  
The only issue I have had is that the statistics can never tell you 
which stems were the most missed because they are just placeholders.
