so need some advice, I was ranked first in my class for modern, gaining the top mark in our first two assessments which were both worth 20% each. But in my half yearly I stuffed up MAJORLY. Wrote a terrible essay and ran out of time in my last section which I can guess has automatically forfeited 8 marks, let alone the marks I will lose from my essay. Point is - I did horribly especially for my usual standards. People weren't originally far behind me and I can't imaging they did as bad as I did in this exam. It was worth 15%. I know that there was obvious issues with my essay technique and I know exactly what I did wrong. I can't change the past so I don't want a lecture about that. Ultimately what I want to know is how much my rank is going to suffer??? Sorry if this made no sense..

Ok guys, so.. I'm trying to see if others can help predict what type of ATAR i will receive. I know its still very early in the year (we haven't yet completed half-yearlys) so i'm obviously not expecting an accurate prediction. But i want to know if i'm being realistic about my aims (90+). My subjects & predicted marks are:
Business Studies: 88
Legal Studies: 85
Modern History: 93
Studies of Religion II: 88
English (Advanced): 87

Again - i'm not expecting an accurate answer, but is a 90+ atar feasible given my subject choices and marks?
Thanks
