I have a media studies assignment set for homework due Monday that has to be within a 500 word limit. I am at exactly 900 words but may have to write more...Can you help me.

This is actually not necessarily for media studies assignments...Many other subjects [including science] have written assignments with word counts.

 

[below post ways you can lower how much you have typed/ how to stick to a specific word count.]

Proofread for repetition, verbosity and points made that just aren't all that important. Get rid of weasel words like "I/some people think that...". For a very, very short essay, remember that examples/evidence/proofs/critical arguments aren't needed for every single point.
