Thank you, I think I get it know !!!!
Also, (this may sound really dumb for an ext 2 student) but can you explain what a good thesis looks like, because often when teachers compliment or criticise my theses, I don't know what they're talking about (lol)
I just know it establishes my argument, but what does a strong thesis statement look like? And can you give me an example?
thank you!!!!!!!! 
No worries! Never dumb at all banana, the only dumb ones are the ones who have the chance to ask a question but let it pass them by

So my rough formula for a good Thesis is something like:
1 - Establish my big concept/idea, my main theme (EG - Discoveries are bad, something broad!)
2 - Give any extra detail required, and link this idea to the requirements of the Module.
3 - Introduce the text(s) as an example
4 - Briefly summarise the arguments you will make throughout the essay
5 - State the ultimate conclusion that you will reach
Here's one from my Module A essay I wrote for my CSSA Trials (under exam conditions) - The essay got a perfect score
Traditional opinions in regard to the nature of the human condition have not remained static, but rather, have developed and changed across contexts. Thus, composers across time will continue to consider what it means to be human in different ways, as to remain relevant to their contextual purpose and audience and to universal responders. Such can be seen in comparison of Mary Shelley’s gothic horror novel, Frankenstein (1818), and Ridley Scott’s postmodern tech noir film, Blade Runner (1982). Scott, in consideration of what it means to be human, has extrapolated on issues first considered in Shelley’s context, such as the natural order of humanity, the human emotional condition, and notions of mankind’s ambition. In comparing these two generic texts, we can determine that Scott has composed an effective consideration of these issues, appropriated for a contemporary audience and form.
Notice I play with the order above a bit, but you can see how in the first two sentences I introduce an idea (what it means to be human) and link it to the Module requirements (how texts change across time, in my case). Then I introduce the texts. Then I introduce the ideas I will explore - Note that in this case I say Scott built on the ideas of Shelley, because
that was my question, how Scott built on Shelley's ideas. Then I state my conclusion, which also has my evaluation in there to satisfy the requirement of
Evaluate which appeared in my question

Thesis paragraphs are tough! It takes lots of practice, but I promise if you write them a LOT, you will develop the skills you need to smash one out on the spot like this
