I have often encountered the fact that certain questions require diagrams, flowcharts and tables etc... What kind of questions and which subjects in particular does this most apply to? I have the following optionals:

Economics (diagrams apply)
Public Administration (?)
Sociology (?)
Philosophy (?)
US History (?)

And from the compulsory modules...General Science is a plausible guess...where would I find the time (and the nature of questions) that demand these? If what I can write in step-form, enumerate or list (Like research methods we discussed at length) Will there be a need to show them through flowcharts when essentially it would be representing the same data?
