    Actually yeah as fluff said, 99 raw with 1st internally seems like a decent cut off this year

    According to some sources, 98 raw was attained by one of the lower state rankers last yr (somewhere between 8 to 10th). But they may not have been 1st internally. My suggestion is that 97+ would've been like a good cutoff in previous years, but this year probably higher (unless they mark...

    Sorry I messed up there- forgot this was a hyperbola not an ellipse.

    I really wish I chose to pursue my hobbies (which was math) instead of doing what would be appealing to our family image.

    I don't think so- what about vertices on y axis? You have to deal with a quadratic for those. Also you considered only one vertex on the x axis

    Oh wow, I guess I'll retract my previous statement then. Good on you either way - do you plan on pursuing mathematics in university?

    Yeah the bos trials are great actually. Am disappointed that you let someone get over 70% though. Naw I am just kidding, well done to both your team and that individual

    Yeah so it seems to be the case that while top students would've absolutely loved this exam cause free marks (or hated it because it was too easy and boring), students at the e3/borderline e4 level struggled with the paper. This really reminds me of the case with the 2013 HSC paper

    You probably got 486 by plugging values into the expression in the 2nd last part. However this gives the total number of ways under the assumption that not all colours have to be used. To remove these cases, firstly note that it is impossible to use one colour to colour the grid, so we consider...

    I do not intend to create any deliberate offence, but could those who say that this paper was harder than previous years please elaborate specifically which part of the paper they found hard? My students and their teachers seem to agree that the paper still followed the trend of getting easier...

    I'm 60% sure you're joking but in case you're serious, what makes you think this year's cohort is stronger than last year? I'd say that last year's cohort was much stronger
