MC Score Types
For an answer of type mc.matrix or mc.multiple you can not only set the score factor with \score
but also choose between different alternatives to compute the score based on the user's answer.
Usage: \MCScoreType{<type>}
Type |
How the score is computed |
1 (default) |
(TP - (FP / (N + 1) ) ) / T |
2 |
(TP + TN) / (P + N) |
3 |
(TP - FP) / P |
??? |
further types will be available in the future |
TP: true positive, FP: false positive, TN: true negative, FN: false negative, T: all true, N: all negative
Remark: The commands \score
and \MCScoreType
are only available within an answer, but not on question level.

If you want that the students only gets points if all choices are correct, use the \allMustBeCorrect
instead.
