This year's want that bad besides like a few of q14 everything else was chill

I thought it was a great exam. The clock question was novel. A much better exam than extension 2. Probably on same level of difficulty as last year.

does anyone have solutions?

yeah

What about a copy of the exam paper? I'd love to have a look at it and compare it to 2024

Did people get V/U = square root of K for the projectile question

nesa have a embargo on it till tomorrow because students in other countries in different time zones haven't sat the paper yet,

the argument i had with trebla before is kind of working out in my favour

and i don't like it

i wish he were right

but he isn't

not many people knew about the embargo before because it was poorly communicated by nesa

knowledge of it is now gaining traction however

 

[v.tex]

Hmm i would say harder than last year maybe a bit easier than 23

 

[v.tex]

I got a bit rinsed on 14 tho couldn’t figure the projectile one. Clock one was pretty easy

 

[BionicMango]

Guess I'll wait until tomorrow then lol

 

[v.tex]

Also I mind blanked so hard on the binomial easy one on 13 f me

 

[regality]

Also I mind blanked so hard on the binomial easy one on 13 f me

OMG SAME i’m so pissed bro

Feeling pretty good about this exam, from the look of those solutions, question 10 is only one I immediately know I lost a mark on. Will have to see if my working was good enough and I didn't make any mistakes for all the others

 

[v.tex]

I reckon 14 was more challenging than most of the other exams tho

 

[nowomansland]

are the people saying it was good do 4u bc

 

[yenisei]

I never have to think about math again hell yeah

14 didn't seem too hard. Fairly obvious pigeonhole principle for a). b) was a bit of a difficult mechanics but it was fairly straight forward. c) was changing an expanded compound angle back to the single cos. d) was a bit poorly worded about what it actually wanted you to find. I put down a piecewise for -1 and 1 where it was defined but idk. e) basically impossible unless you realised you needed to expand tan(alpha + beta + gamma) and use sums and products of roots
