    Mathematics Extension 1 Exam Thoughts

    Will there be a penalty for not drawing the diagram for circle geo? I genuinely did not see that instruction.

    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    LOL! I just need a few, so I'm asking here to see how many marks some incomplete questions would warrant.

    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    For circle geometry I showed angle BPC = BCP =ø. Therefore OBC=2ø(exterior angle...). And OA = OC(radii). OA perpendicular to AQ and OC perpendicular to CQ(tangent perpendicular to radius). And I proved Triangle OAQ congruent to OCQ(RHS). Would that be 1 mark or 2 marks? :confused2:

    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    Well I hope they give me benefit of the doubt. I hope it's not naive to consider that 1 mark is already guaranteed - and that this is a dilemma between 1 or 2 marks.

    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    I initiated my working like this: Consider x≥1 (as we are given x≥0) (followed by the working I showed you above) It's rather badly worded, as it seems like I'm getting the fact x≥1 as we are given x≥0 which virtually makes no sense......But I hope they overlook that somehow. Or perhaps...

    Mathematics Extension 2 - 2016 Post-HSC Exam Thoughts

    For the inequalities question, I just showed this, how many marks would it get? It doesn't prove for 0<x<1, only for x≥1. Maybe 1/3 or 2/3? :/ x^2≥1 x^2(x-1)≥(x-1) x^3-x^2≥x-1 add 2x√x to both sides x^3-x^2+2x√x ≥ x-1+2x√x x^3+1+2√x ≥ x^2 +x + 2x√x (x√x +1)^2 ≥ (x+√x)^2 x√x+1 ≥ x+√x

    Transferring to actuarial at UNSW

    Hi everyone, I'm currently in year 12. I'm hoping to do actuarial studies at UNSW next year, however there's always a chance I might not get it. In that case, my alternative plan is to do Bachelor of Commerce / Bachelor of Science (Advanced Maths) (Honours) and then transfer as soon as I can...

    Transferring into actuarial studies

    Hi guys/girls! I'm currently in year 12, and in the worst case scenario that I don't get into actuarial studies, I was wondering, how difficult is it to transfer into actuarial after doing a year of another course, say software engineering? Thanks!

    UNSW Co-op

    Hey guys, is anyone here a Co-op scholar? I have quite a few questions with regards to not only this, but the entire UAC application process itself (I'm a current year 12 student). Firstly, how and when do applicants find out if they're successful for an interview or not? Thanks

    Actuarial/Adv maths at uni

    Hi everyone. I'm currently in year 12 and I'm going for co-op Actuarial studies at UNSW. I was just wondering, they also have advanced mathematics for co-op. I'm unsure of the difference and which one to put as my first preference. Could someone please clarify? Thanks! :)

    eco raw mark b6

    Hey guys, Obviously the scaling varies from school to school for internal assessments (based on rankings), but in the actual HSC, what raw mark (approximately) would get you a band 6 in economics?

    atar estimate please

    School rank: ~35-40 software: HSC mark: 93 3u maths: 17/64 4u maths: 14/19 eng: 70-80/165 economics: 18-20/43

    atar estimate please

    Are you sure? Even entering my raw marks into a calculator is outputting 87, which in itself would be inaccurate especially for 3/4u maths, economics and possible english as they scale high.

    atar estimate please

    School rank:low 30s Maths Ex1: 17/64 Maths Ex2: 14/19 Economics: 20/43 Software Design/Dev: 90%, highest mark 93% (ranking would give false indication as everyone else is bunched into the same percentage) Eng Adv: 70/161 Thanks!

    another atar estimate please!

    Hi again everyone, can I please have an estimate: School rank: low 30s: 4u maths: 14/19 (16 band 6s last year) 3u maths: high 10s (15-20) / 60 (like 30 band 6s last year) SDD: 7 people in cohort. Very strong cohort, let's assume 5-6 people will get band 6 (I'm probably 3rd-4th) (3...
