Hi again Joe,
I had the same problem when I joined, in that you can't be good at everything and for me that meant that English was by far my worst subject at school. But I wanted to be a pilot so I had to pass that test so here's what I did.
I thought, what are they going to ask me to do?
Write an essay, probably by giving me a topic and a limited period of time.
Now what's the subject going to be?
I picked three potential topics:
Defence of Northern Aust
Characteristics of a good leader
Why did I want to be a pilot
I then took my time and wrote out, with help, how I would answer those questions. I then practiced and practiced until I could do it perfectly.
Then I did the test, and low and behold I got characteristics of a good leader and I aced it!
It was the best of all my assessment scores, I always have a smile on my face when I think, if only they knew…. Mind you they found out later when I had to do the bloody writing skills cse
Hope this helps and if this is what you want to do, then it will require all of your commitment.
P.s I would like to say that I did this a while ago (1987) so please don't think that you will be asked to write about one of these topics specifically.
