Multis and Q11-14 slightly harder than past years. Q15 and 16 were easier than recent years.
I'm guessing aligning will be worse than previous years?

I've known people to not get 100% in maffs exam due to writing 1+1 =3

2 plus 2 is 4, minus 1 das 3 quick maffs

 

[dollaking]

I screwed up really bad... You reckon 45% raw will make it into the E3 range

 

[RandomNG]

I lost like 4 marks on Multiple Choice alone, Baited by Q6 and all 8~10 (according to current consensus). Only hope is that I didn't screw up anything else for an 80 raw.

Last year in my 3U exam, I read a question wrong. And in my 4U exam, not only did I also read a question wrong, I did 2 x 1 = 1...

I probably still hold the record for most stupid mistakes lol. In my 4U trial, I bubbled an answer different to the one I thought was correct (and was).

lol 2 marks for an induction question

I guess that's because the base case was basically given

 

[fluffchuck]

What raw marks do you reckon would state rank?

I'm guessing 99% raw, not too sure though.

 

[shervos]

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 ridiculously to distinguish all those 100s).

 

[shervos]

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

Yep and n = k + 1 was pretty straight forward with just an application of the assumption n = k and part i

 

[ishan]

really easy actually, 88+ raw according to carrotstick's solutions

 

[EngineeringHelp]

Does anyone have a copy of the exam? Or knows where i can get it?
Thanks

It's on nesa's website now: http://educationstandards.nsw.edu.a...7/mathematics-extension-2-2017-hsc-exam-pack/

 

[xuvu6520]

I think I can safely say that NESA has run out of good questions to ask

I completely agree!! Some questions were actually in my Revision and Assessment Tasks for my students.
However, only the results can speak for themselves. We just have to wait!

*When you did the modulus instead of the argument. Rip free marks.

Yo, do u guys think i'll get an e4? My internal mark is 88 (rank 6 in a top 30 school) and I'll probs get 80+ raw for the exam (based off solutions) ? I need those bonus points for UNSW lol

Yeah probably, since around 70-75 is B6
