Scoring rules and formula

The score for an exercise is based on the point value you set for the exercise.

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.
  • Final score never goes below 0 (no negative totals).

Example 2: two or more correct answers​

Exercise score: 1 point.

  • Each correct alternative adds 0.5 points.
  • Each incorrect alternative subtracts 0.5 points.
  • If a learner selects two correct and one incorrect: 0.5 + 0.5 - 0.5 = 0.5 points.
  • If selections would drop below 0, the score is set to 0.
