I think so- like, you have your dominant theologies and like, your side-line theologies...
Even if the module does not state it, I think it's a good idea to have a good knowledge of the different ideaologies and be able to apply them even if it is not required- for example, I'm in the middle of the Hamlet/Rosencrantz thingo and we've been told to look at different readings as well as the notion of Transformation (haven't done this in class yet but through transformation, dominant ideaologies can change!!! This in turn changes the entire emphasis of the text, conveying different meanings).
When studying and comparing different readings, you want to look at what the different readings are concerned with and how they interact with other readings- for example feminists are concerned with the role of women whilst liberal humanists tend to be more inclined with wordly messages to and about humanity. Each will argue that it is the most important reading- look at what they say, and compare them, ie "____ agrees/argues that/goes on to suggest.." etc.
Best wishes!
