Is there any way we could hide the marks allotted for every question in a MCQ from the people trying to attempt a quiz?
The only way to change that is to edit the code.
In mod/quiz/locallib.php, find the function definition "public static function make_from_quiz($quiz, $when) {". You need to change the line
$options->marks = self::extract($quiz->reviewmarks, $when,
self::MARK_AND_MAX, self::MAX_ONLY);
Change MAX_ONLY to HIDDEN.
Thank You Tim.
