    What is the hardest Maths Extension 2 topic?

    Yea agree with this. HSC physics has such minimal maths but on a conceptual understanding level physics was really useful for vectors and mechanics.

    4U & Advanced.... advice

    The other option is to go through the advanced content inside and outside of class at your own pace (likely far faster than that of your advanced class) and then spend significantly more time on ex II and ex I

    Is Rawmarks database reliable?

    I’m pretty sure they ask for proof of your Rawmarks when you submit (ie ask for the pdf straight from NESA). Also, when putting their data into excel and graphing it I haven’t noticed any obvious outliers so far (although with so little data it’s kinda hard to spot outliers)

    vectors mcq

    If the left hand side of the fourth one had absolute value signs around it, it would be true

    Physics predictions?

    yea bro, this is confirmed in the phys exam

    Physics predictions?

    Let P(n) be the given proposition Prove P(1) is true 1 = 1(1)^2 ∴ P(1) is true Assume P(k) is true E = mk^2 Prove P(k+1) is true RTP: E = m(k+1)^2 ∵ trivial and left as an exercise to the reader ∴ P(k+1) is true ∴ By proof by mathematical induction, P(n) is true for all real n ∴ E = mc^2

    Question 16b ext2 2022

    Pretty sure that got discussed in this thread https://boredofstudies.org/threads/maths-extension-2-thoughts-and-feelings.401616/ If I remember correctly, the consensus was that for the downwards trip the velocity now going down) is defined as positive so the air resistance (which is still...

    should i do french for my hsc?

    Nothing French specific, but +1 for doing accelerated subjects

    First in state without having the highest HSC Mark

    Possible yes but improbable. Could probably only happen if person A wasn’t ranked first internally meaning their assessment mark would be less than 100.

    Mathematics Extension 1 HSC thoughts

    ur not alone, I ended getting an unsolvable quadratic (k^2+k+1)

    Can 65% raw mark for ext 1 math this year scale to e4?

    Also interesting to note is that the alignment for 2020 and 2021 3u was quite similar. whether that means this years will be similar alignment again or way different (like 4u was from 2020 to 2021 - see 2nd graph) 4u alignment:

    I need to stop reading this thread and discovering all the mistakes I made 😭😭😭

    Unfair HSC Exam Schedules?

    I agree it’s a bit unfair but there isn’t really a perfect solution. No matter how they allocate the exams someone will get a bad timetable. At least they notify us of the timetable months in advance

    Mathematics Extension 1 HSC thoughts

    Yea, once scaling gets applied the person whose HSC mark ended up being 100 instead of 90 gets a significantly higher aggregate (which contributes to ATAR) Pretty sure UAC doesn’t even look at the HSC aligned mark, they only look at the raw marks

    pretty sure / i hope so that's what I got

    Walked out of the exam thinking I completely threw but everyone seems to have find it fairly difficult.

    Physics and No Maths.

    I agree that HSC physics has fairly simple maths. But the type of people who do 0 units of maths presumably have weak maths skills and might find the physics maths challenging (challenging is probably too strong a word, but the point I’m trying to make is that someone who does maths will be able...

    Generic writing booklets

    pretty sure the only difference is the number of pages in them
  20. Vall

    What do you guys think of the Ext 2 Math scaling this year? Would it be better than previous years?

    If you are "scraping" an E4 with your raw marks then you will definitely get an E4. Even for extension 1 the alignment is pretty crazy.
