Answer 1

I am using the following Marking Scheme:

>=90 : Grade 'S'

>=80 and <90 : Grade 'A'

>=70 and <80 : Grade 'B'

>=60 and <70 : Grade 'C'

>=50 and <60 : Grade 'D'

>=40 and <50 : Grade 'E'

<40 : Grade 'X' : (Failed)

I am using an array to enter the test score, so as to reduce the repeatative tasks for each test scores. My script can easily be generalized to N test Scores by replacing the 5 with the value of N. Thumps up if you liked the answer.
