Asignar automáticamente puntos/marcas a preguntas de opción múltiple

Question

Estoy creando un examen con preguntas de opción múltiple y preguntas estructuradas. ¿Cómo asigno automáticamente una calificación o un punto a las preguntas de opción múltiple para que cuando recopile el trabajo el número total de calificaciones incluya las de las preguntas de opción múltiple?

Answer 1

Modifiqué \questionel valor predeterminado a 1 punto, por lo que debes usarlo \question[0]para asignar puntos por partes. No pude encontrar una opción para suprimir los puntos de impresión, así que solía \pointformatcrear una.
