When partial scoring is on, the learner receives credit for any correct responses submitted but is also deducted credit for any incorrect responses submitted. If the score is negative, it will be scored as 0.

Here’s an example multiple choice question structure that has two correct responses and two incorrect responses.

- Correct Response 1
- Incorrect Response 1
- Correct Response 2
- Incorrect Response 2

Let’s first look at the possible scoring if the question's Maximum Selections setting is set to two selections.

If partial scoring is off, the learner must submit a perfect response or they will receive 0%. So, the possible scores are:

- Submitting 1 and 3 – 100%
- Submitting any thing else – 0%

If partial scoring is on, here are the scoring possibilities:

- Submitting 1 and 3 – 100%
- Submitting 1 only or 3 only – 50%
- Submitting 2 and 4 – 0% (technically a deduction of 100% but negative-value scores are set as 0)
- Submitting one correct response plus one incorrect response – 0% (credit of 50% for the correct response but deduction of 50% for incorrect response of 2)

If the question's Maximum Selections is set to four, the learner will have more “opportunity” to submit incorrect responses under partial scoring.

For example, if the learner submits 1, 3 and 2 they will receive credit of 100% for the two correct responses and a deduction of 50% for the incorrect response for a total of 50% on the question.

If they submit all four choices, they will receive 100% for the two correct responses and a deduction of 100% for the two incorrect responses for a total of 0% on the question.
