Diagram / Model Style

Hello.

Please could someone clarify is there is a default style of model/diagram if it is not explicitly stated, or is the preference up to the modeler.

For example: Assignment 4 Question, the tut answer is in Chen Model, would it still be okay too model it in Crow's Foot and still get the marks.

Thanks

Although looking at the question again, now I think CHEN Model deals with the M:N relationship better than CROW'S FOOT in that Question, so maybe the simpliest solution is the best solution.
