[t101]

Hi team, here are an initial set of suggested solutions.

if you see any errors, please log them here and I'll update later: https://docs.google.com/spreadsheets/d/1obtfeRDsR24BwZWFKqc_kb5o9WnoqsvD4jZPfAiVGBs/edit?usp=sharing

If you're a current methods 2020 student, perhaps wait till after tomorrow's paper before looking, but whatever works best for you.

updated: 5a and 6c updated based on feedback. thanks!
6b - coordinates need to be labelled - I'll update this later

what did ppl get for the value of k to have the shortest distance from point P to f(x-k)?

f(x) in this question was a positive quadratic with a minimum greater than 0. P is (1,0). The y-value needs to be as close to zero as possible, which occurs at the minimum. Therefore the minimum needs to be at x=1. In f(x) the minimum is at -3/2 and we're translating k to the right. Hence k must be 5/2 because 1 - - 3/2 = 5/2. I see someone else already beat me to posting the answer but hopefully this helps anyway haha.

I think I did alright, except I wasn't able to figure out the required forms for the double area and binomial questions ;-;

It was good on time. It's just sad because I think I'll do reasonably high but not extremely high, and I've been very consistent in that range (might scrape by with a 40 or so, unless I'm completely deluding myself).

(Based off of the solutions posted above) I managed to get every question except for the double area question.
I have to say though, it was a pretty tough exam; much harder than any of the past (VCAA) exams I have done.

How are we thinking the cohort will perform on this exam compared to past exams?

do you think VCAA will accept decimals for that one probability q??

[emilyswag]

so hard?? so different from every other exam

[khaiv710]

If it makes anyone feel better I got about 2 marks out of 40 right. Whoever needed to hear that, you're welcome.

do you think VCAA will accept decimals for that one probability q??

If it is the exact value you should be fine. E.g. if the answer is 1/10 and you say 0.10 it is fine. However, if the answer is 1/3 and you write 0.33 it is wrong.

what did people get for m in terms of n on the probability question?

[janu28]

Hi, umm can i get a good score if i lost like 2 marks??

[dylan.kumar21]

If it is the exact value you should be fine. E.g. if the answer is 1/10 and you say 0.10 it is fine. However, if the answer is 1/3 and you write 0.33 it is wrong.

Thank you!

I reckon the cut off might be lower than last year's which is already pretty low lol

[Jemin99]

This year's paper was definitely hard, harder than 2018 and 2019 for sure, we will see how exam 2s gonna be like

gon 2 cri.

the entire exam was a curveball. i did the 2016, 2019 and 2018 with no major issues. but this exam was something else. i think it may have to do with the fact that i didn't account for timing, so essentially all questions were answered half-answered despite knowing i would've been able to do everything fine but i really overestimated how much time 1 hour would be. super frustrated. was hoping for a raw 40 but at this point, anything over a 36 will do.
