ui_style.points_box_position number

At which percentage of the height should the Points box container start

Default: 60
feedback_attempts number

If instant_feedback is true, this field determines how many times the user can click on the 'Check Answer' button. 0 means unlimited.

Default: 0
instant_feedback boolean

Flag to determine whether to display a 'Check Answer' button to provide instant feedback to the user.

Default: false
validation object

In this section, configure the correct answer(s) for the question.
validation.allow_negative_scores boolean

Negative scores will be normalised to zero by default. Allowing negative scores, on the other hand, means that the score can drop below zero when penalties are applied.

Default: false
validation.penalty number

Value indicating the marks deducted for an incorrect response.

Default: 0
validation.min_score_if_attempted number

Positive value indicating the minimum score if a student attempted the question.

Default: 0
validation.scoring_type string

The way in which marks are distributed for the question. Possible options:
'exactMatch': Exact Match - All parts of the question must be answered correctly to receive a mark.
'partialMatchV2': Partial Match - Each correct response element will be scored individually, and the overall question score will be divided between responses.
'partialMatch': Partial Match per Response - Each correct response element will be awarded an individual score.

Default: "exactMatch"
validation.unscored boolean

When enabled, this option will remove all scoring from the question. This is useful for creating practice questions.

Default: false
validation.valid_response object

An object containing the valid response score and value.
validation.valid_response.score number

Score awarded for the correct response(s).

Default: 1
validation.valid_response.value array

An array containing objects defining the correct position for a given point, e.g. {point: '3', position: '3'}
