Hello!
I was wondering if this paragraph made any sense as I am analyzing my related text in response to each module C people and politics rubric dotpoint, in this case that of the relationship between textual form, medium of production and language choices and how these choices influence and shape meaning. Please tell me if there is anything I can improve on! 
The relationship between textual form, media of production and language choices influence and shape meaning as explored through “To Kill A Mockingbird”. Novels as a textual form allow characters’ thoughts and feelings to be clearly expressed to the responders, enabling for a thorough exploration of this novel’s racial politics and prejudice through the perspectives of several characters and therefore permitting the responder to form their own evaluation of such topics. Language choices in “To Kill A Mockingbird” also distinguishes between characters, such as those of Bob Ewell who mostly speaks in extremely colloquial language (“She was mighty beat up” ) and Atticus Finch who’s constant high modality language (“I am confident that you gentlemen will review without passion the evidence”) demonstrates his higher intellectual capacity and depicts Bob Ewell as a racist, prejudiced fool, therefore conveying Harper Lee’s intent of condemning negatively used racial politics and discriminatory prejudice.
Thank you in advance! 
Hey, I'm just a current student so take my advice with a grain of salt, but I'm guessing from your text that you're doing People and Politics? I'm doing the same, so hopefully I can be of some help

I think this is a good line to run, but markers will really reward it if you can condense it down a bit and you'll have more time to dedicate to your analysis. People and Politics almost always requires you to identify the political comment the author is trying to make, and crucially, how they represent this. You have both of these elements (racial politics/prejudice + novels as a textual form), however they're raised separately as two different sentences. If you can make a succinct topic sentence that combines them you'll be absolutely ace.
To combine these elements, consider basing your analysis around characters and characterisation, as A) your analysis is based around characters already (Bob Ewell and Atticus Finch), and B) characterisation and the representation of characters is an aspect of novels as a form. You can also add depth by bringing context into your argument.
Your current topic sentence very clearly alludes to the rubric, but you'd save space and make your essay more accessible to exhausted exam markers if you nod to it by weaving it into your argument and analysis. Try to strike a balance between subtlety and an unmistakable reference to the focus of the module.
So, something like: "In Harper Lee's 1960 novel,
To Kill a Mockingbird, the racial politics and prejudice of civil-rights era America is represented in the portrayal and interaction of the novel's characters" could tighten your topic sentence. If you wanted to run a different form argument altogether, you could say that the 1930s southern USA setting is used to stage Lee's 1960s civil-rights era commentary on racial politics.
That said, I'm basing my advice solely off what teachers at my school have told me, so if your teachers say you should be doing anything in a specific way, that's the way to go.
