    UNSW imposes minimum entry score of 80+ ATAR

    Of course it's a publicity stunt. By imposing this benchmark they'll seem more 'prestigious'

    How many weeks off after trails?

    I think that you're still required to go to school after trials, just after you've finished the course at school some people rather study themselves then go to class for revision

    Equation of Tangent

    Best way to do quotient rule questions at first is to identify v and u so set it out like this f(x) = x^3/x^2-4 u = x^3 v = x^2-4 u' = 3x^2 v' = 2x vu' - uv' all over v^2 2x(x^2-4) - 2x^4 all over (x^2-4)^2 and then expand and simplify.

    Equation of Tangent

    Depends on the school mang, you've seem to have 45% already assessed? so have 55% left so it might be split up into 30% and 25% if you have only 2 assessments left. depends though.

    Trial Discussion Thread.

    Probably say 5 max for trials... really depends on the person i.e my friend from NSB didn't do any trials papers just did solid revision to consolidate everything and then did questions didn't sit specifically and do past trial papers.

    haha ahh, yeah I simplified the -6 even further :L dunno how I got confused over dat :L

    Equation of Tangent

    are you sure the asnwer is -6? I'm getting -2 +- root 30 /3 Basically you have to simplify the surd, you have your answer -24 +- the sq root of 480 all over 12 right? 480 = sqroot(16x30) = 4root30 and from that you get -2 +- (root30)/3

    Tutor or Non-tutor

    A bit modest there, Deswa! I think for tutoring it depends on your teacher as well, i.e they may not be able to explain it well or miss content, etc. If you're able to understand concepts fine and are doing well with your personal study then there is no need for you to get a tutor, see how you...

    Equation of Tangent

    Depends on your school ranking, really depends on your cohort can range from 90%+ or 80%+ depending on overall difficulty of your exams etc.

    Urgent!! Do not know what to pick!!!!

    If you're worried about workload I have a friend who does All 3 sciences, and Extension 2/1 Math. As well as others who do extension 1 math + all 3 sciences or atleast 2 sciences and ext 1 and 2. It's manageable. I think chemistry would be a better pick because it's more important to have the...

    Equation of Tangent

    Differentiate, since the derivative is the gradient function, sub dy/dx = 14 to find the values for X so 6x^2 + 24x + 18 = 14 6x^2 + 24x - 4 = 0 Use quadratic formula to find values of x for the gradient of the tangent to equal 14.

    Didnt put enough effort for maths- advice ??

    One of my mates was getting 30% (Who just does 2U) In Prelims now he's like top of his 2U Class, so he's doing well. Just put some effort it, the only real "Basis" for year 12 2U is Calculus and Term 1 stuff/revison i.e abs value, surds, factorising, etc.
