A COPY OF THE EXAM.

I gotta say... I struggled with it. I don't know my mind was asleep or if the exam was actually quite hard, but I found myself unsure how to approach a handful of questions. Didn't arrive at a definitive answer for a few, but at-least displayed some method.
Oh well. Onto exam 2!

Exactly how I felt, exam didnt feel super hard but I was just thrown by it :(
Is a 25-30 still possible if I end up getting like 15/40 on this one? Generally do better on exam 2 so say 45/80? Ranked ~15/40 in an average cohort.

Not bad! The last question was a bit tricky though. Took me about five minutes to realise that it was just the area under the arc cosine graph not the volume rotated around it

last question asks for volume 0.o

It wasn't too hard, but I don't think I got a single answer right, all my marks would come from working/consequential :/
-
Not happy about the slope curve question because it was super vague on whether I was doing the right thing.

What will be the A+ cutoff this year? Also can someone please predict my study score:
Exam 1: 39/40
Exam 2: 78/80, 76/80 and 74/80
-
last question asks for volume 0.o
Yeah, the volume is essentially the area under the arc cosine graph times by pi because you square f(X) and it's just the integration of arc cosine. I thought at first it was asking for the volume rotated by the arc cosine graph and had a bit of a pickle.
-

I am totally in the same boat. I at least started every question but didn't get a final answer for most of them, even though I would say overall the exam was very fair and wasn't too hard. Hopefully we can pull it together on part 2!
-

They'll have to be lenient with our answers, so don't worry about it.
-
Did anyone else guess x=1.9 for the estimated value of x based on that slope curve sketch?
-

Well I calculated x=√(11/3), so its between √(3) and 2, 1.7-2 should the the correctish range

What did you guys get for qn 3? Solving for z?
-
Thoughts on mark allocation for question 4 if I momentarily caught autism and said Pr(z<-2) = 1-0.025=0.975
Fingers crossed it will only cost me one mark with adequate working?
-

z=1+-i and 3

Do you remember what you got for this question? I had two answers, 2pi^2 and 2pi^2-2pi, depending on what I chose for the terminals. I left it as the former one, between -2 and 2
Oh damn, I just remembered. I messed up Q.6, i gave the domain that would have been for a one to one sin function instead of arcsin...

Hey man, I know you did spesh at decv. Neale Woods or Georgia Gourous? Don’t worry too much about exam 1. It is done and dusted. For exam 2 l, just aim to do your best. It shouldn’t be hard if you got 17/20 for the multichoice questions at the exam seminar.
-
So annoyed, for the last question I originally didn’t it from -2 to 0 and then with 30 seconds to go realised it should have been 2 rather than 0, changed up all the answers and got 2pi^2 after crossing out the -2 that I had from my original answer which was wrong, I had it written as pi(2pi-2) and crossed out the -2 but never actually expanded out the pi... any chances of still full marking that question or would they take away a mark for not expanding?
-
For the second last question on the displacement of the particle after 10 seconds, was the answer suppose to be in vector form. Will I loose all 3 marks if I didn't give my answer in vector form? :'( :'( :'(
-
i realised that the terminals from the last question were meant to be -2 to 2 just now... :'( :'( how much marks will i lose from it if i did everything right except the terminals?
-
Is it still possible to get 45+ if you get an A for Exam 1. I stuffed up two questions on exam 1
-
Was anyone else as *intelligent* as me and say the probability was 0.05 instead of 0.025 :'(
-
Has anybody posted up solutions yet?

Can u still get above 45 if u stuffed up exam 1 (like lost around 3 marks) but aced exam 2?? :'( :'( :'(

is it possible to get a 30 ss if i got 17/40 minimum on exam 1?

I stuffed up too. Lost around at least 3-4 marks....... :'( :'( :'( :'( :'( :'( :'( :'( What would be the cut-off mark for A+? Can I still get above 45

That's exactly how I felt. The exam wasn't hard but I struggled to get to a definitive answer( minus those questions that I clearly couldn't do because of my silly mistakes).
Is having a goal of 37-42 too far fetched if I lost about 10 marks on Exam 1 but score around mid A+ in Exam 2 ?
-
hahahaha i'm actually shit without my cas.. already lost a minimum of three marks, don't even wanna look at the answers..

Hey, Another fellow DECV Student. Do reckon our SAC marks would scale up ? According to the box plots they gave us after the SACs, our cohort seemed pretty strong. The SACs weren't usually hard (except the last one, it was terrible for me) but is there still a scope for scaling up ?

if i went further than r(10) and found the magnitude, will i lose marks?

yes, only 1 mark though

Does the domain in question 6 worth 1 or 2 marks??

Does the domain in question 6 worth 1 or 2 marks? I think i lost at least 3 marks. Will i still be able to get above 45 if I aced exam 2?

It's not that a has to be positive, but that one of the solutions is extraneous (in that if you sub it in, cos theta becomes negative half rather than positive half) I think. I forget which solution I rejected though
Does the domain in question 6 worth 1 or 2 marks??
3 marks, I reckon one is for the proper derivative, one is for recognising the domain of the original function, and one more for stating the correct domain by not including the original endpoints. At least I hope, because then I might get two marks instead of losing two

Here's a copy of my solutions - they are mostly the same as Worm's, although I've approached some of the questions a bit differently, so I thought it might be worth uploading anyway in case anyone was interested :)
RE Q5: I agree with JOHNSMITH II, and I've checked the solutions by substituting back in
EDIT: I'm not too sure about the answer for Q4: my answer assumes the 68%-95%-99.7% rule, but others have said 0.023 could be the answer.
EDIT2: Also let me know if there's anything you don't agree with - these answers aren't 100% :)
EDIT3: Answer to question 4 has been revised - thanks to MathMethdz99-R

How did you express displacement, as a vector or vector magnitude, and why?
-

displacement is a vector quantity since it specifies both magnitude and direction so it should be expressed as that i think, basically if you take the magnitude of it you're just getting a distance from it without the direction

i think question 4 should be 0.025 (instead of 0.250), how did others get 0.023? i also assumed 68 95 99.7% rule.

The actual value to 3 d.p. is 0.023. That rule is just an approximation (but I think 0.025 will be accepted).

Thanks so much for that! It's been fixed :D
The 0.023 comes from the actual value (if you used your calc) - since 95% is only an approximation. I used 0.025 since I assumed VCAA wanted us to use the 68-95-99.7 rule, as it was non-calc.
-
0.025 will be accepted I don't think 0.023 will be (even if it's the MORE correct answer)
-
What exam score would I need on exam 2 if I got about 33/40 on exam 1 to get at least a 30 study score?
-
I am 99% sure 0.023 will NOT be accepted.
The question ASKED for the APPROXIMATE probability to 3 d.p. - hence only 0.025 should be accepted.
It DID NOT ask for the PROBABILITY to 3 d.p - in which case 0.023 would be correct.
-

I think 40-45/80 would do (not 100% sure though)

Hi guys I got 27-30/40 (not really sure what the marking scheme is like and if I'd get consequential marks for arithmetic errors made in the first step) for exam 1, and am scoring about 60/80 on exam 2s. SACs have been in the 75% to 85% range, in a pretty strong cohort. What study score can I expect to get? Sorry for posting this here but I'm kinda desperate :S
-
So if i were to get 38/40 for exam 1, do I still have a chance at 40+ in spesh, and if so, what exam scores might i need for exam 2?
Thanks (and gud luck to all for exam 2 :) )

38/40 is certainly enough for at least 40 as it is likely the A+ cut off will be 37-38/40. If you get 72+ in exam 2 you should get a 40+ SS

Back in the day I got a 43 with a scaled 94 for my SACS, 38/40 on Exam 1 and 74.5/80 for Exam 2.

This exam is so tricky that different from previous exams and lots of different questions.Yesterday I had reviewed the 2015/2016 exams and also the North Hemisphere one,but it does not work either.I got wrong answer on question two by applying incorrect separation of the fraction.
-
Well it is fairly challenging but definitely less tricky compared to the methods one. (Especially the slope fields question and the probability one)
Kinda expected since methods is always like that.
Also, would 1.8 be accepted instead of 1.9 for the x-value in the slope fields question? Since it's an estimation that feels fairly vague.
I'm standing at a 37-38/40 at this point, so hopefully I'm able to get a raw 40? That's my goal.
-
I think I got 50%-60% on exam 1
what marks on exam 2 approx, for 35
-
I think I got around 35/40 for exam 1. If I have ~98% SAC marks, rank 4 in a decent cohort, could I get 40+ still? If so, how would I have to go in exam 2?

It is a really sad story of I just got 44,40,84 for three sacs.Ans Also my exam 1 is nearly around 30/40,I just wonder how much score could I get and if I need a redemption next year(this year I did not do method because it clashes with physics)

if i got 30/40 for exam 1, what SS would i get if i got 70/80 for exam 2?

if i got 30/40 for exam 1, what SS would i get if i got 70/80 for exam 2?
around 35 :)
-
What marks do I need in spec exam 2 to get a raw 33?
Sacs (85%)
Rank2 in a below average cohort
Exam 1:
best case 22/40
Worst case 16-17/40
Thank you
-
If I’m ranked between 3-5 and have a sac mark of 82, with a really strong 1&2 (who probably score 45+) and I scored 30-36/40 on exam 1, can’t remember my answer for one of the 4 markers and not sure about consequential on other question, what exam 2 score would I need for a 35 raw?
