Re: General Thoughts - Maths Extension 2

What mark do you reckon you will need to get into the E4 band.
Is 80/120 doable?

Re: General Thoughts - Maths Extension 2

I thought the exam was fair. Easier than last years..yet i had poor time management.
Finished q 1-4 in and hour..and then i got stuck on some 2 markers..so i left out q8 completely in the end

expecting maybe 70-80/120 raw..

Re: General Thoughts - Maths Extension 2

conics went out with a bang.

lots of people are predicting 115+ at my school, surely someone will get full marks this time around.

Re: General Thoughts - Maths Extension 2

i loveed that maths exam i was expecting something freakishly hard. knowing i only got one wrong so far, im hoping for about 114 +/- 5 marks /120 give or take due to silly mistakes. hopefully though this time around i dont make any and i get 119 / 120 id be stoked man

Re: General Thoughts - Maths Extension 2

sigh that test was by far the easiest one yet
all the questions were doable
but i worked to slow and only got the first 5-6 marks in q8 before times up
like 40 ppl in my school (out of 120) said they finished the test:(
and so far quite a few said theyre expecting 120 or close enough to it
i reckon to get e4 now u need around 95

Re: General Thoughts - Maths Extension 2

Yea it was more like an extension 1 paper.
Multiple results of over 115?... you're school's pretty freak.
I reckon I might've scraped 115.
That last question was tricky, but i got pi squared/2 cos sin pi/2n approaches pi/2n as n approaches infinite... did anyone else get that?

Re: General Thoughts - Maths Extension 2

same difficulty as last year.. (i also sat the 4u last year)... which are both definitely easier then the rest of the hsc's
stressing about time and sloppy work lost me many marks...
q8 did'nt look hard, only time consuming...

expecting 85ish/120...

btw is scaling a constant + x% ? or does it vary somehow...

wow yes! i got pi^2/2 as well, same reasoning. i almost forgot about the sinx->x for small x, but luckily i remembered. Hopefully that's the right asnwer :)

Re: General Thoughts - Maths Extension 2

I was quite happy with it. Breezed through question 7 + 8; lots of "show" questions, so I think I only lost one or two marks there.

Borked up the probabilty question (I can never wrap my head around those) and the trig one.

So, I'm pretty sure I missed out on 9 marks overall, not including silly mistakes, but a 105+ would be very pleasing. :)

And I agree; tons of Conic. The whole of question 7 was pretty much conics. :S

Didn't get up to the last mark, but I still probably wouldn't have thought of that.

Overall, left out the last mark due to time constraints, screwed the probability, and did ok in the other questions, so just have to wait now till the results are released. I do agree that there is a good possibility that someone could get full marks with this paper in the 3 hours, it wasn't really that difficult and time really was the only issue there.
