Yeah, no worries, man!
I'm HSC 2005 by the way, so I'm just as inexperienced as anyone else
The marks you're describing aren't bad, bro. Most of my classmates average 14-15 in any of their 20 mark tasks. They could be better, though, but I just want you to know you aren't screwed or anything. You have plenty of time to pick up, and provided you really deliver in the HSC exam, you can redress anything that's happened (to an extent)
First of all, reports and essays. What's the difference? Although I'm sure there may be differences, neither I, nor my teacher, have ever found any cause to distinguish between the two (you should note, however, that
essay is the most commonly used term hereof). As to tightening the screws on your essays to start pulling those 18-20s, the advice I'm able to offer on this is limited, and, furthermore, the work I'm able to do to help you is almost naught (unless you want me to tutor you or something, but I'm in Byron, so... ya, good luck with that one!
)
There are a few pointers I can throw your way, though. Firstly., don't throw away your past papers or burn them or anything like that. The only way you're going to improve upon deficiencies is to identify areas of weakness in your work, learn from them, and take measures to ensure they don't happen again (or, at least, not too often). Hang onto your stuff, ask the teacher as much as you like about the places in which you've been penalised and, yeah, don't view these things as failures. Look at them not as disasters but as positive events from which you can learn and grow.
Of course, you need to synthesise and seamlessly integrate statistics and examples into your argument, which, never forget, is what any essay is. It's like English without all the bullshit
Just make certain you're always well stocked on facts, figures and such, and, above all, make sure that you know your stuff! Actually understanding the Economics and, in particular, the actual syllabus content, will boost your marks tremendously, without you even knowing it
Finally, try not to think or worry too much about structure and the fine points of essay writing, especially during the actual exam. It will take you enough time as it is getting everything you need down on the paper without you agonising unnecessarily. Just relax, be confident, and all these fine points should just flow.
Oh yeah, I could fax in a few of the essays I got full marks in if you want, or my past exams, if you think tht might help, but remember that the improvement must come largely from you and your own actions.
I hope you get something worthwhile out of this. Hope I've been able to help. Cya!
