Please add an additional scoring mode for Multiple Choice questions in which only correctly selected answers contribute to the score.

The scoring logic should work as follows:

Correct answer selected → predefined number of points
Correct answer not selected → 0 points
Incorrect answer selected → 0 points
Incorrect answer not selected → 0 points
Example

A question contains five answer options:

3 correct answers
2 incorrect answers

Scoring:

each correctly selected answer = 5 points
each incorrectly selected answer = 0 points
maximum score = 15 points

Examples:

Selected answers Score
1 correct answer 5 points
2 correct answers 10 points
3 correct answers 15 points
2 correct + 1 incorrect answer 10 points
Only incorrect answers 0 points
All answers selected 15 points

The resulting score should automatically be included in the existing Assessment total score.

Benefits
This scoring model is widely used in:

• Knowledge tests
• Competency assessments
• Certification exams
• E-learning
• Training courses
• Educational and research environments

Currently, this behavior can only be achieved through complex Equation workarounds or external calculations.

Providing this scoring mode as a built-in feature would make it much easier to create knowledge and competency tests and would significantly extend LimeSurvey's assessment capabilities.

Suggested Implementation
For Multiple Choice questions, an additional scoring option could be introduced, for example:

• Standard Assessment (current behavior)
• Award points only for correctly selected answers
• Award points for correct answers with optional penalties for incorrect answers

This would allow survey designers to choose the scoring model that best fits their use case while remaining fully backward compatible with existing surveys.
