[LON-CAPA-users] Correct selection of optionresponse

[Stefan Bisitz]

Hi Christian,

One Course Coordinator might want to show the correct answer after two 
tries to his/her students, another after three tries. Think about 
leaving this choice to the coordinators, so do not hardcode it in the 
problem.

A course coordinator can set the parameters in the course, e.g.
Set "Show Problem Status" to "Yes, and show correct answer if they 
exceed the maximum number of tries."
combined with "Maximum Number of Tries".
