mine was above the x axis the entire time and had a min at that area where it was nearly flat. why did nesa choose to spice it up this time, and what is the chance both 3 and 4u papers had an extra booklet
chance was very high after the x2 had a booklet, honestly the amount of just mistakes made in that paper by me think my x2 raw mark percentage will be higher then x1

yeah i did a similar thing and went past an x=intercept then up
I just made a dot to dot for all the direction field things going through P. Kinda concerned because i thought it looked absolutely fine, but the solns given above look very different. Mine looked like this:

well i did similar except mine went to a x-intercept after the y-intercept and then up but then again that was my first time drawing a solution to a direction field so probs wrong

Haha same dude, coming out of that exam i think i nailed everything except the very last question, but after looking through the paper i realised that i just misread like so so so many questions. The volume one, bounds, area, literally got the right answer for q8 in the m/c but coloured in the wrong one 🥴 ah well rip :\

Yeah i dont recall exactly how i did it, i just remember not going nearly as far down as the one in those solns lol

the concrete volume is like a 1 for me, the projectile motion i accidentally made a t disappear meaning i couldnt do the ceiling bit, q14 literally looking at the solutions i had everything write but for some reason it never gave me the answer for some of them and q14a) misread thought wind was going south, never knew comprehension skills in maths were this poor :/

also where was the trig calc ik one multiple choice but really? I swear trig (not trig calc) is like in both yr 11 and 12 and a big part so how only like 5 marks

Bruh, same fr fr. the very last question, i had everything pretty much set up correctly, and then just thought to myself "nah nup nope, you're not getting this". Same for the population of deer question, everything set up perfectly, just thought nah, had to just sub 1 number in to get the answer lol. Pretty sure the cohort of 130 or smthn in Ruse, are all getting 68+/70 lol

the deer thing just annoyed me with how little space i had to write and the large numbers they picked

what makes you say this. tbh the exam was kinda simple just the binomial one was very poorly worded, as with the standard one as well

just so happy the nesa gods answered our prayers and combinatorics was like 3 marks 🤩🤩🤩🤩🤩🤩

the 5theta/7 one was substantial.


for this one i had a really convoluted solution using auxillary and ended up with a nice sine thing then i realised shit its sine rule so ye
the sin theta thing was 4 marks all up, idk just expected more, there was no aux angle except multiple choice

ye ik but i used auxillary for the plane one because i solved simultaneously using vectors instead of geometry and trigonometry

i did it correct except i had wind going south not coming from the south... Definitely more of a physics question then maths though

Your following comment "the exam was kinda simple" makes me say this ahaha, think we're on the same page here. Not only ruse, but practically 90% of all selective schools, hell, anyone good at x1 (who cares enough to read the question properly lol), is gonna get a raw 68+/70 in this.

so do you reckon scaling would be better or worse this year compared to lasts.

imho, worse, unless a lot of people around the state were just like me and didnt know how to read lol. Thought that paper was pretty free until the very last question pretty much, and q10 a little bitta thinking. 4u and Adv will 100% scale better, i did 2u last year and that was an absolute pisstake ngl, most people i know, finished that paper with like an hour and 40mins left, 2021 adv on the other hand much harder. My maths tutor got 99 in x2 last year and she said this years was a fair bit harder so thats what im deriving from. She also got 100 in x1, and said this year was easier, i guess that serves as a confirmation bias for me, which is why i still reckon 2021 x1 was easier than last year.

mine dipped a bit lower do you think its still valid
im sure itll be fine. Slope fields just have to be fulfilled in those regions where it shows those specific gradients. Tehcnically, you could have a total spazm in the middle of 2 of the dash's, and it 'technically' be correct.(cuz if they havnt given you a specific formula, then who knows what happens between the bounds 0.68<x<0.70, just as an example). Although thats a pretty risky approach, i dont think itd be advised for anyone to do that lol
