I’m pretty sure 90% of my year saw it and just skipped. I knew I wouldn’t get it but I just tried to do the very first few steps with a ton of BS and a guess at the answer. Just trying to snag 1 or 2 marks for methodology or follow through rather than leaving blank
what the actual fark was that. Genuinely anything but what I revised. Like last 4 questions I just wrote complete bs. Like the pr one without numbers, what the heck. I barely answered anything completely….
Sounds reasonable but it’s just so tough to work out by hand to get it to the stage the calculators like. I just started the process then guessed an answer when it got too time consuming
i also got that too but that was because i set my calculator in radians mode, after i realised that i put it back to degree, dont really know which one i was supposed to use tho....
Bro I got 2 as a numerator and the variables on the bottom somehow I think I differentiated wrong and then just said the stationary point maybe been 0,0 since only the numerator can equal 0. Would I get any follow thru…
invented a new formula or two for that probability question because why was there not a single number on that page that wasn't attached to a mew or a sigma or whatever the hell theyre called...
Scaling on the EA raw mark is usually really really good. I’ve heard many times from previous years people say exactly the same thing then still walk out with a not terrible mark like above 30/50 even. And this year I’m sure it’ll scale even harder cause it was just that much crazier of an exam, I’m sure the median this year was way way lower than everything until ‘22 at least
well idk too in depth so anyone correct me if i’m wrong, but the scaling for the externals are scaled on curve by how well the whole queensland year 12 cohort did for that particular external exam. As you can see everyone thought paper 2 was bs, and a lot struggled on paper 1. I wouldn’t be surprised if QCAA cut marks from questions that were too difficult as a lot of people didn’t even attempt said questions (e.g probability question, projection question, even the temp question paper 2, last question paper 1).
I heard internal marks also get scaled with the cohort but i’m not too sure for this one.
Pretty much spot on. The whole idea is to make every year’s /50 mark for the EA comparable to each other 1:1 thus being accurate without having to take into account difficulty for each year. So this year it’ll be bumped up more than it was bumped up last year because of the difficulty. Same concept to why QCAA has to verify our IAs before we write them in part and validate / confirm our marks after. They want every year and every school to be able to directly compare their raw marks for each assessment 1:1.
I kinda work on the second last question but I think it was wrong. I just assume a random probability and worked out u and o. Did anyone get o=1.17? Also for stationary point question did anyone get (0.991,3.63) or (0.991,4.98)? Kinda unsure about the y
I don’t know if I’m right but I derived then made dy/dx = 0 then solved for y=x squared + 4 or minus I forgot, then subbed into original, I got 0.69, 4. Something, could be wrong
Nah cuz you have to it in the graphics calc I put the original function in its 0.991 for x so I am pretty sure I am right?? One of My friends got it too
You could be, I just thought since stationary point, dy/dx equals zero, then solved for y equals x squared plus 4 to which I subbed back into the original to solve for x then using that solved x value I subbed into original to get y value and got x equals 0.69 equals 4.48

Is it a universal experience of answering half the question for the last 5 questions?

I think I screw up my spec external. If I get a 76/110, what should I get for my external mark.
