If you have any practice essays/creative you want feedback on-I am willing to have a look over it and give you some detailed feedback-it will be better if you also attach marking criteria, just pm me, but in the long run, there are many companies that does marking-usually quite expensive as well as well as you can always get your teacher and get a tutor to mark it for you
I would never be able to mark a creative sadly. Nor could my teacher. So I had to find the teacher in our department who actually does HSC creative writing marking. I had three creative's, and eventually one was really good and filled up my 3-4 mark gap in paper 1.
I'll jump in for marking the structure of essays though (thesis writing and stuff).
