How did everyone find it?
-
absolute wack. The questions weren't difficult but I ran out of time and had no time to double check nor finish the exam. Also the probability binomial question omg :(
-
Anyone know how to do the last question? :P
-
What did people get for the second area for the double area question?
-

I think I got (5-2root2)/6
-
Lol what a time pressured exam...
The questions weren’t stupidly difficult like 2018, but there was medium to hard questions scattered throughout the paper which made it difficult...
I feel like such a dumbass though, I skipped the tan question to do the harder questions and ran out of time and didn’t get to answer anything for it...
-
-7 wasn't suppose to be included........right?
-
yeah it wasn't defined for X = -7, as X+5>0
-
I think I got (5-2root2)/6
I got that too!
-
do you guys think that it was harder than 2019 e1? idk how to feel about it, I feel like it would've been better with more time lol
-
Overall very happy. I was struggling with a question but realised I just messed up my arithmetic and corrected it. Otherwise, trickier than I expected but still super confident with it. Timing was tighter than practice exams but I still finished with time to check my answers.
-
I royally screwed that up... so many dumb mistakes...
-
yeah it wasn't defined for X = -7, as X+5>0
Was the other solution x=-1?
-
I got that too!
I got close to that - my answer was wild so I guessed. :-\
I was very annoyed - I never ran out of time in the numerous practise exams I did!! And this one I left five marks blank. The last ones. Ones I could do. >:(
I mean I think I did ok, but not well, at all. I liked a lot of the questions, but still, a lot of it I knew I got wrong. :(
-
what did ppl get for the value of k to have the shortest distance from point P to f(x-k)?
I got k = 5/2
This was when the turning point of the curve was directly above the point P(1,0)

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??
-
so hard?? so different from every other exam :(
-
If it makes anyone feel better I got about 2 marks out of 40 right. Whoever needed to hear that, you're welcome.
-

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

Thank you!

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

I feel you man - the questions weren't the worst but damn time flew by, it wasn't even as hard as the 17/18 paper but I think I did worst in this one
-

i got something similar to that. i'm so dissapointed
-
Anyone know what exam 2 score I need to get over 30 ss? Did quite badly for exam 1 today (12ish/40 :'( ). We had easy sacs, small and weak cohort of 4 people. Average 92.5% on sacs. If anyone can help I would really appreciate it.
thanks!
Don't stress too much, especially at this point, and honestly it'll all depend on tomorrow's difficulty. This year's exam is definitely gonna be curved so the cut offs will be pretty low. But I reckon for 30+(assuming lower than last year's average), a 50/80 ish will do
-
can't really not stress though :-\ haha but thank you so much for your reply
Legit in the same boat tho - hopefully E2 can save
-
pretty crazy how the night before i was thinking about how i have literally no idea how to do any probability questions, yet i didn't study them at all so i just laughed at myself when i opened the book and those two page long probability ones were there haha. don't feel like studying them tonight either to be honest :>
-
I studied probability all weekend (only learnt it on Friday, any of it) and opened the book and saw it and went I know this, then afterwards the rest of my class got out and said What was that awful question on binomial stuff, and I just thought This is what I studied for...
-
Probably the most difficult exam 1 VCAA has given. I made a couple of dumb mistakes and ended up with 38. Will have to be sharp tomorrow.
-
I got k = 5/2
This was when the turning point of the curve was directly above the point P(1,0)
Yeah, I got the same. It was essentially just a translation of the graph to the right along the x-axis by a factor of 5/2.
-
For E2, just did 2019 exam2 found it alright... but I know from today to not expect it to be similar :) but like does anyone actually use their summary books, I find it so useless and time-consuming. What would you guys recommend having in the summary books?

Anything you might forget!
I personally have one page I use often, which is a double page, essentially a map of CAS functions with explanations how to use some if I think I'll forget/haven't used them much. Then I have summaries of everything else in the SD, more for more if I need them, including worked examples, and then at the end tips to remember when checking through questions, how to avoid stupid mistakes, etc.
-
So I messed up my answer on one of the questions so I crossed it out and then put the answer on the blank page at the end. Will the examiners accept this answer on the back page?

As long as you put an * on the question and notify them about your answer being on the back page.
