A good rule of thumb for any higher mark question is evaluate, evaluate, evaluate (then evaluate the evaluation).
Higher mark questions come with a variety of instructions (examine, assess, compare and contrast...) but they all really mean the same thing (you've probably guessed it - evaluate).
Evaluation can take different forms but an esay thing to remember in an exam is strengths and weaknesses. When you've written something (perhaps outlining an idea for example) try to stop and think and say to yourself "Yes, But..." - that way you're constantly thinking about how you can be critical (and "criticism" here can be positive - highlighting what something explains well - as well as the obvious negatives.
Being critical can also, if you have the nerve to do it, mean questioning the question - in this instance you could question the whole premise of "deviant subcultures", for example, but don't ever go overboard here; always try, ultimately to focus on what the question's asking.
Also, if it refers to "the Items" use them - easy marks here and a good way to get you started on a question if you're feeling nervous. Once you've settled into the question then bring in your wider knowledge.
