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 manners for computing the score:
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 |
4 (only mc.matrix) |
column-wise |
??? |
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.
Example: Select all true statements

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