I’m finishing first year uni and still don’t know what I wanna do it’s chill we’ll figure it out

I’d say no 2020 and 2021 were both kinda hard but not too bad 2022 and 2023 were much harder So I’d guess 2024 and 2025 will be similar Also aligns with the fact that question writing teams are generally hired for 2 years

I’ve heard your multiple choice was crazy though

Anyone got a copy of the paper?

Ahh cool

Or what topic anyway?

What was the question for 14 (a)?

Fair

Nice to see you doing this again :) Your concern about 16 (b) (ii) caught my attention -- I haven't thought too much about it and I may have made a mistake but I think it's really just a case of induction. If you consider the sequence of unordered sets S_k =...

Presumably your big time sink is finding square roots of complex numbers. For some inexplicable reason schools very rarely teach this well. Consider that you want to find a number x+iy such that its square is 3+4i. By squaring both sides and equating real and imaginary components you get the...

Surely geometric or combinatorial mathematical induction I was hoping for this last year in my HSC and it never came … surely it makes a comeback?

Also I thought I'd also mention in response to 'other textbooks' I did mention Steve Howard before, which is freely available online. I'm not thrilled with his exercises though ... they seem to vary greatly in difficulty (I found his complex numbers exercises generally very easy with a couple...

Look everyone's going to have a different opinion on this but here's my two cents: The Cambridge Textbook is designed to have an incredibly wide range of questions - from the most basic to the hardest. The intention is to be able to cater for students at different levels. The HSC is designed...

Was there a spark gap Hertz-like effect?

Wow that’s so cool, thank you so much!

Thanks for providing solutions! Can I just ask for the polarisation question to be clarified please (Q26)? If we assume 50% of light is polarised in x direction and 50% polarised in y direction, then I would think we get the following equations when passed through a polariser: I_{max,x} =...

Studying… :(

lol I didn’t take Chem but a mole happens to be the one thing I kinda get (or think so anyway … don’t test me Chem ppl)

How are you like almost SR in like every STEM subject there is and then are suddenly crazy at English as well?

Ahh okay, thank you Would you not expect the actual chemical composition of the stars to be different? Like presumably a main sequence star still has hydrogen while a red supergiant does not, so you'd expect the lines to not just change in thickness but in position as well? What have I...
