Ill tell you what I used to do. I used to get pretty good marks for creative writing (althought cant say much for the other sections)...
Pick a topic that you're really passionate about and write about it.
In one of my trial exams last year I wrote about the Israeli / Palestinian issue. Now how the hell is that a journey? Well, I personified myself as a teenage settler with two parents who were settlers (and no I am absolutely not related to any of that situation). I wrote about the gut wrenching emotions that I had personally seen on the news and pretty much made them a part of the personality of the persona.
Are you really interested in broadway?
You can find a journey in almost anything. Pick something (real life) that you're passionate about and make a narrative around it.
Be easy on yourself. You can actually personalise something that is going on around the world. Maybe you could write a story about being in Southern Beruit during the Israeli / Lebanese war that just happened, and write about your escape. I am not saying you should write about this specific topic, but I am sure there is some world event which you know quite a bit about which you could write about. The more extreme, the more gut wrenching, the better - that is what sticks out.
Oh and one last thing: Stay away from LOVE STORIES... they're boring and teachers (aka markers) hate them.
Oh and your english teacher is still your english teacher until you sign out. So write a story, and take it into her/him tomorrow to have a look at. If your teacher is away, take it to another.
