Was your 'exam' a speech? What did you do wrong?
- If it was a speech, well don't worry too much about it since the HSC exam doesn't actually test you on speeches. It tests you on your ability to reproduce essays that you have perfected in class and then adapt it to the question (key terms etc) :]
- If it was a test, what did you actually do wrong? Many things could be worked on over the holidays as ^^^^^^^^^^^^^^^^ have stated. If the test mirrored the 'AOS: Belonging' part of the HSC exams, perhaps you didn't re-edit your essay enough etc etc etc...
Also, I am guessing that the weighting was 15% so that if you just 'barely' passed, then I assume that is ~55%. That is 8.25%/15%. I think that in-school assessments account for 50% of the total mark in the end so that is 4.125%/7.5%. That means you have lost 3.375% out of a possible 100% from your end of year mark without all the scaling and aligning and whatever (I don't know anything about those things). I don't know if this is right but I assume that it won't impact TOO drastically on your ATAR unless you keep getting ~55% on all your assessments.
Sorry if any of this was wrong, I was just trying to give some of my own advice.
