## Scoring

### "All or nothing" mode

| Answer                  | Points |
| ----------------------- | ------ |
| All correct, none wrong | 100%   |
| Missing one or more     | 0%     |
| Selected wrong one      | 0%     |

### Partial credit mode (optional)

Points proportional to correctness:

* 3 of 3 correct = 100%
* 2 of 3 correct = 66%
* 1 of 3 correct = 33%
* Wrong answer = penalty

## Best practices

<Tip>
  **Hint in question**: State how many answers are correct, e.g., "Select 3 correct answers" - it's fair to participants.
</Tip>

### Question content

* Clearly indicate multiple answers allowed
* State number of correct answers (optionally)
* Avoid "select all correct" without indicating how many

### Answers

* Minimum 2 correct answers
* Ratio: \~50% correct (e.g., 3 of 6)
* Incorrect answers should be plausible

## Example
