Does Ruby can accept Operators?

I tried to used greater than or equal to in my when keyword, but it didn't work. I worked with number.

print "Enter student score [0 - 100] : "
score = gets.to_i
grade = 'unknown'
case score
when score >= 90
  grade = 'A'
when score >= 80
  grade = 'B'
  puts "Great"
when score >= 70
  grade = 'C'
when score >= 60
  grade = 'D'
  grade = 'Not Passed.'

if grade == 'Not Passed.'
  puts "Sorry, your score was : #{score}. In that case, you are #{grade}."
  puts "Congrats. Your grade is : #{grade}."

Hey Fadli,

I haven't run any tests on this, but I think it may have something to do with your conditions. In the first one, you are checking if "grade" is equal to or greater that 90 which will assign an "A". However, the next one is checking if it is greater than or equal to 80 which will give a "B"... the problem here is that greater that or equal to 80 could also be greater than or equal to 90. (You see the conflict?).

Try adjusting your conditional to be something like greater than or equal to AND less than 90.
