    why is: *case obj * and not: case obj.class

    If you're doing the same thing for each case, a case statement doesn't really make sense in my opinion.

    Here's a predicate that includes all of the conditions:

    [Hacker, Submission, TestCase, Contest].any? { |clazz| obj.is_a? clazz }

    You can use string interpolation (like in truesdell_trent1's comment here ) or just concatenation (with obj.class.name) to output the class names.

    def identify_class(obj)
    # write your case control structure here
    case obj
    when Hacker
        puts "It's a #{obj.class}!"
    when Submission
        puts "It's a #{obj.class}!"
    when TestCase
        puts "It's a #{obj.class}!"
    when Contest
        puts "It's a #{obj.class}!"
    else
        puts "It's an unknown model"
    end 
end
