I'm not doing conflict this year, so this may or may not be relevant to your context. But I'd done conflict last year so I may have a good idea what you may be on about.
For Expository, you will need to follow quite a rigid structure, which as follows: Intro, Para 1, Para 2, Para 3, Para 4, Conclusion.
Since expository is the most popular type, you will need to make yours different and stand out from the rest. So on your introduction, you will need to start with something interesting in your introduction, be it a quote, anecdote, story, analogy or anything that can that intro, yours.
You will need to plan based on your topics that you have been given. You
must adhere to the prompt (if you don't you lose a hell lot of marks). For planning, it see it as being two main ways.
Method 1: plan from the topic down to the examples.
Take the prompt "It is though conflict we grow."
First, imagine someone said this to you. You would want to ask this person some questions such as:
- Can we not grow though conflict?
- In what ways do we grow though conflict?
Then, use these questions to make your point, which will be the points you would want to write in your essay. Con up with ~6. You can eliminate them later down to 3 or 4.
Using the example above, it is likely to be:
We grow more mentally though conflict; We grow physically through conflict; We do not grow from conflict that is too much for us; we can choose not to grow from conflict; and so on.
Look for examples. Cut out the points you don't have examples for. Combine points if you can. Once you get down to 3 or 4 points, write the topic sentences for each point. Take the point above "We can choose not to grow from conflict." I could make it a topic sentence which would sound like "Often, we choose to not mature* through the various disputes* throughout our lives, thereby disallowing us to grow from conflict."
Once you have your topic sentences, you can start writing.
Method 2: Plan from example to topic.
Essentially, this is the inverse of method 1. You start coming up with examples relevant to the prompt. Take the prompt I used above: "It is though conflict we grow." Now, I come up with examples relevant to the prompt such as:
- People learning their lessons after encountering conflict
- People who couldn't cope with conflict become weaker and eventually lead to issues (think mental health
You get the idea. When you have your examples, you group them based on their similarities, can name each group.
Say the groups were: People who grow from conflict, people who don't grow from conflict, people who are damaged though conflict.
Then, use these to create topic sentences for you paragraphs. Using "people who grow from conflict" I could make it a topic sentence that is: "In some instances, people who develop through the quarrels* they come across throughout their lives."
The begin writing.
For external resources, you can see this link:
http://www.vcestudyguides.com/encountering-conflict-external-resources/It doesn't give you specific examples, but it can give you a few areas where you can look for examples relevant to your prompt.
Last year, when I did conflict, I did
The Quiet American and
On the Waterfront as the main texts. You may consider these resources too. Apart from that, anything you read, seen, watched, heard. Honestly, you can even find resources in even the most unusual sources. I even found stuff from a video game.

I hope this helps.
