Set grading criteria up for customised marking allocations for composite answers
To set up marking allocations for composite answers within a single part, use expert mode to add a second string to the grading criteria (after the relative error string) which will allocate the appropriate decimal for each answer.
Add the second string in brackets and use the * sign between strings.
For example: suppose that in a single part, you want a relative error of less than 1%, and you also want three answers, for a total mark of 10, with the following allocations:
- Answer 1 (_0) - /5
- Answer 2 (_1) - /3
- Answer 3 (_2) - /2
The two strings will read (_relerr < 0.1)*((_0==A)*0.5+(_1==P)*0.3+(_2==D)*0.2)
Moodle applies a relative error of 1%, and then gives 50% of the marks if the student’s first answer is equal to the global variable A, 30% if the second answer is equal to the global variable P and 20% if the student’s third answer is equal to the global variable D.
The marks for the various answers within the parts need to add up to 1, even if the whole part is worth more than this.
