I want you to decide whether this tutorial is worth taking and to explain why or why not. Some things to know about evaluation.
Evaluation presupposes some standard of judgement.
If I dislike Bon Jovi's music, it's probably because I prefer Bruce Springsteen. Springsteen is my standard of judgement. This implies that my standard is not really Springsteen but that Springsteen performs to my standards. I like a melody I can follow. I like lyrics that go beyond mindless repetition for 3 minutes of a 4-line chorus.
