Dadas las diferentes notas puntuadas de los alumnos. Necesitamos encontrar calificaciones. El puntaje de la prueba es un promedio de las calificaciones respectivas obtenidas en tareas, exámenes y trabajos de laboratorio. El puntaje final de la prueba se asigna usando la siguiente fórmula.
10 % of marks scored from submission of Assignments 70 % of marks scored from Test 20 % of marks scored in Lab-Works
La calificación se calculará de acuerdo con:
1. score >= 90 : "A" 2. score >= 80 : "B" 3. score >= 70 : "C" 4. score >= 60 : "D"
Además, calcule el promedio total de la clase y la calificación en letras de la clase.
A continuación se muestra la implementación:
