Grade Calculator

Write a program that determines a student’s overall grade. Ask the student to enter marks in 3 subjects, English, Maths, and Science. For each subject, the score will be between 0 and 100. It then calculates the student’s grade based on the following rules:

  • If the average score is 90 or above, the grade is A
  • If the average score is 80 or more and less than 90, the grade is B
  • If the average score is 70 or more and less than 80, the grade is C
  • If the average score is 60 or more and less than 70, the grade is D
  • If the average score is below 60, the grade is F
