A professor may want to create a multiple choice question and allow students to get partial credit for choosing some of the choices. For example:
a. Completely correct - 100% of the grade
b. Partially correct - 70% of the grade
c. Partially correct - 70% of the grade
d. Not correct - 0% of the grade
A new box would need to be added to the Add/Edit Question user interface that would allow the instructor to enter in a % value for how much this choice is worth.
This would need to be set up so that the instructor could either:
1. Check a box to mark that a question is the correct answer. In this case, no partial credit is given
2. Enter in a value into the % box. In this case either full credit or partial credit could be given. If nothing is entered into the box, a value of 0% is assumed. If the instructor checks the box that signifies this choice is correct, a value of 100% is assumed.
