I think with the negative marking factored into it, those that scored above 30 are definitely covered cos that represents about 50% in real scores (Not sure about below 30). Flour mills will decide the cut-off they want to use. Just stay proactive while you wait and apply for other jobs, develop your self and work on improving your writing and speaking skills. I am sorry to say that i see a lot of "typos" and grammatical errors in posts on this site. My point is....
Just stay busy.
