Hey,
I'm in year 9 and I have this awesome teacher with an awesome teaching method.
He's made this powerpoint with heaps of sample introductions about the text/film, and then we copy them down to get a feel for how long they should be and how much info they should contain. He also has heaps of sample essay topics and he gives us a time limit to write one under pressure.
I think maybe you could ask your teacher to give you some sample introductions or sample introductions. Otherwise, you could always make some up yourself and pick out of a hat, then give yourself a time limit to write an introduction. There's no need to write a whole essay, just make sure you plan your exam time wisely.
After you write the introduction you can give it to your teacher and ask him/her to check it and give you tips on how to improve.
In regards to the text or film you're studying, read or watch it at least twice. For the first time, just concentrate on the storyline and enjoy it. For the second time, write down quotes and/or highlight words.
I hope this helps!
