When I did the 2013 paper I thought it had the easiest last question I've ever done in a 4 unit exam. Honestly I had a lot more problems with Q15 than Q16. Was 2013 really that hard?

I'm expecting a significantly harder exam. Probably a hard binomial question. Maybe a difficult related rates one.

When you sit your HSC exams you will usually get some mark between 0 and 100. But the thing is, each year the exams vary in difficulty so an 87 in 2017 may not be the same as an 87 in 2018. And obviously, an 87 in Maths Ext. 2 is very different to an 87 in Maths General 2. So what NESA does is...

The question said "Show that" - doesn't this mean we would basically have to perform the whole expansion in order to do the "showing"? Honestly if we were just required to expand (\cos x + i \sin x)^8 it wouldn't be that bad, but it is also necessary to express \cos^6 x and \cos^4 x in terms...

Did it really have to be to the eighth power though? Wouldn't three or four have been enough...

For q16 I believe it was: a) 3 b) i) 3 b) ii) 2 c) i) 2 c) ii) 3 c) iii) 2

From that site, the previous cutoffs seem to be somewhere around: 2013: 63 2014: 70 2015: 76 2016: 60 2017: 77

I really didn't like that question... What is the point of wasting our time by forcing us to perform so many expansions?

It's $18.10 for the results check (non English courses) + $6.20 for raw marks. http://educationstandards.nsw.edu.au/wps/portal/nesa/11-12/hsc/results-certificates/results-services-students

What do you all think the cutoff for a 95 aligned will be?

I think I would have gotten it if I didnt start with the wrong ratio.

Well I’m kind of worried now because I didnt even get the last part of q15 and probably lost at least eight marks in q16. Definitely not getting 90 raw but I hope my mark can be somewhat close to my trials at least...

They scan your exams so a faint mark would probably not even show up on the screen.

Only if the speed of the body is given to you...

I'm pretty sure you wouldn't be able to know. The direction of the lateral force is dependent on the speed of the body in relation to the design speed of the track. HSC questions should always (and they have) provide a diagram for this sort of question.

I do the first few MC in my head during the last bit of reading time to get myself started and then go on to finish MC first.

Honestly I'm fine with anything as long as it's not a tough combinatorics/circle geometry question. I feel like it might be integration. The current calculus based Maths courses will run for one more year - so 2019 will be the last year. Don't worry that's not going to happen... plenty of...

You can use LaTeX with the tags [Xtex] [X/tex] (remove the red X's). for example, [Xtex] \left( \frac{\pi^2}{6} \right) [X/tex] gives: \left( \frac{\pi^2}{6} \right)

I'm just doing one paper a day. 90 raw would be nice but as long as nothing terrible happens I'm fine with it.

If you really truly have a passion for all of your subjects (not necessarily including compulsory English) then you could try doing 14 units and see if you can bear the workload, and drop later if you feel that it's too much.
