what about q13a) why is it square root y? thought it should just be y

i agree maybe some english teachers have joined the maths team cause ive never read so much in my life for x1 and x2

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

the sin theta thing was 4 marks all up, idk just expected more, there was no aux angle except multiple choice

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

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

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...

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

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

ive heard that it cut off and went both ways, anyway said i got zero to try and better estimate the mark, as soon as the paper said put name on booklet 12 i knew instantly what was happening

yeah i did a similar thing and went past an x=intercept then up

ok no worries

you got any solutions for x1 by any chance yet

just one is an understatement, multiple were made

bar my terrible algebra mistakes i still think q14 was harder in 2021 then 2020, if i had the same time for q14 in 2020 as i did today ngl the perms and combs wouldnt be too bad

fair enough honestly would say more in 2021 other than last part of q14 but maybe you are better at these topics them me

curious about what to you was hard in 2020 and what was hard in the 2021 paper to you

I really dont think this year was easier, all last year had was a perms and combs q

just kinda wanna see the answers/questions to see the mark ill probs get

anyone got pdf of paper/worker solutions also?
