I just want to know if it is possible to change one question correct answer and recalculate all grades.
My question is a matching question with 4 pairs.
1 => A
2 => B
3 => c
4 => d
It is kind of ordering and we did a mistake and the order is not correctly entered. (For example, it is in reverse order.)
Is it possible (and how) to change it to correct order and recalculate all grades, in a matching question type? How it stores user answers in database? can it recalculate? which one I need to change in a pair? question or answer or I can change both?
I know that there is a "regrade" and "Dry run a full regrade", but I'm not sure, IF and HOW to do it.
