Scoring Rules and Formula

The score for an exercise is based on the point value you assign and how the learner selects alternatives.

Formula

• Partial score for each correct alternative = total score ÷ number of correct alternatives
• Partial score for each incorrect alternative = total score ÷ number of incorrect alternatives
• The final score never goes below 0

Formula examples

Examples

Example 1: one of three

Exercise score: 1 point

• Learner selects the correct alternative: 1 point

1 point	0,5 points	0 points	0 points

Example 2: multiple correct alternatives

Exercise score: 1 point

• Each correct alternative adds 0.5 points
• Each incorrect alternative subtracts 0.5 points

Example:

• Two correct and one incorrect:
  0.5 + 0.5 − 0.5 = 0.5 points
• If the result drops below 0, the score is set to 0

Example 2a

1 point	0,5 point	0,5 point	0 point	0 points	0 points	0 points

Example 2b

1 point	0,5 points	0,5 point	0,5 point	0,0 point	0 points	0,0 points
