Question

How can I count the number of appearance of a number within a range?
Ex:
The category that will serve as a guide:
90-100 Excellent
80-89 Very Good
70-79 Good

the output should be...
score 1: 98
score 2: 99
score 3: 89
score 4: 100
score 5: 75
score 6: 80
score 7: 99
score 8: 76
score 9: 78
score 10: 90

Excellent = 5
Very Good = 2
Good = 3

I appreciate your help :)
