Can anyone predict the A+ cutoff... I think the exam was relatively harder than all the previous exams... lost 8 marks I reckons... (couldn't do the last few questions cause I spent too much time on the Ferris wheel....)

Also my study score...

Exam 1: assuming 37/40
Exam 2: 64/80, 70/80, 72/80 (just incase I made any other stupid mistakes)

Oh the joys!! ;) ;) ;)

=> My Method for every practice exam I have ever completed; Start from the start and work my way through, always finishing, no problems.

So what did I do today I hear you ask? WELL MY FRIENDS, I started at Question 2 for Short answers, skipping the first because "It's easy calculations, I'll come back to it later". So I rode a ferris wheel for a while, then had to study for at least 20 minutes but no longer than 70, made it to question 4, had a great time there and finished that bad boy. I then proceeded to the MC and began those, being the jetson I am, with 5 minutes to go I was up to 19, finished 20, then exhaled as I was SO relieved.

In this sense of Euphoria, I turned the page, and my heart Dropped, no like it literally hit the floor. I had COMPLETELY FORGOT ABOUT THE FIRST QUESTION. I managed to salvage two marks before pens down.

There is a lesson to be learnt here; DO NOT FALTER from what you have always previously done. OR run the risk of being as dejected as I am right now ;)

50.

MCQ was pretty easy had to skip 2, ended up getting one but forgot to shade in the bubble lmfao. Had to guess the Australian survey MCQ.

Exam went down hill from finding (u, v) on the Ferris wheel. Pretty sure my method was correct but my calc could not evaluate it.

Did it another way which gives me different values but it's 100% wrong since my v was less than 65.

Anyone know the 'correct' way?

---
I didn't finish though lol. I wrote stuff for most questions but didn't have time to go back and re-do the ones I know were wrong for certain.

Definitely harder than last year's exam 2.

Hahaha nice one. I did something retarded too.

I skipped MCQ18 (sd = mean for binomial question), came back to it and did it. I circled the answer but forgot to shade in the bubble. The lady says pens down and I double check my MCQ and nothing was shaded, I freaked the fuck out and forgot what was the correct answer, so I shaded D when I knew it was E.

Since I didn't ace exam 2 like I said I was, I guess I needa compensate and get a 50 in spesh 🙄🙄🙄

I am just imagining the disappointment settle across the examiners face in my face. I would take 1 MC question over x amount of marks I lost from forgetting lmao.

To be honest, I wouldn't even be surprised at this rate if I got a higher SS for spesh, I am well and truly halfway there. Best of luck with the studies :)

Multichoice seemed standard if not a bit easier than normal. But extended response felt like a massive challenge. It felt much harder than 2012 or 2013 exam 2, but I think that my vision is probably clouded by the stress of the exam. Hopefully the A+ cutoff is as low as those years, but it probably won’t be and I’m probably just overreacting because of the stress. Anyone else feel this way?

Yeah. This exam's ER felt like a combination of Qs from 2012/13 and 2016, but on steroids.

Regardless of difficulty, the A+ cut off won't change by much. Too many einsteins.

Well my school is full of Einsteins and even most of them found it very difficult. If it’s as hard as we think the A+ cutoff will be like low 60, like in 2012 and 2013, which I’d be happy with. But, if it turns out that the A+ cutoff is like mid to high 60 and it wasn’t as hard as I thought, then I’d be really annoyed.

Man I felt so bad for letting my cohort down tbh, until I checked AN.
Everything was okay until the ending of the ferris wheel one, and the absolute last question about the area.
So here are my scores (as of now I think) if any kind soul might want to predict my score (I'm in the top 5 in an average-decent cohort with 15-20 40+ scores every year):
SACs: mid to high A+ (scaled to a 100 internally)
E1: 37/40
E2: 65-73/80

Mhm, Honestly I wasn't really a fan of this years, as opposed to the 2016 exam and even 2013 onwards; I found this years to be quite challenging. MC I agree was pretty stock standard, maybe the population sampling ones were a bit out there. Can 100% agree that SA were a hurdle, I think they might be trying to push methods back, as in; making it more difficult than it has been in recent years. Would be expecting a low cut off for A+ marks this year, and 2016's were already respectively low, hence why I believe they're testing the waters to try and find a happy median. Nonetheless the cohort will be separated this year. You are not overreacting, I feel the same.

What would I get if I get 38-40/40 exam 1 and 72-75/80 exam 2? I’m ranked reasonably well in an extremely competitive cohort. I hope I end up scoring this high but wouldn’t be surprised if I did much much worse. So I’m trying to be optimistic.

Sorry for all of these questions, but would 39/40 and 79/80 be a 50?

Hard to say, as usually you'll require a 40/40 to even have a chance of a 50. This year's exam was quite easy, so unfortunately I think you're more likely to get a 49.

I thought that was fairly tough, relative to other VCAA papers. My (hopefully correct) solutions are below (file size too large to attach here).
https://drive.google.com/open?id=1xomM33jx7QvY7CAnnErVjaOJYhk9Bzcb

I believe MC 5 is A, not c. You would add the two values and then divide by two, because each value should differ by the same amount from the sample proportion

With 38/40 in part 1, maybe 72,73 /80 in part 2, and ranked 1, what SS might I get?

Yep, I've just picked that up looking at the second set of posted solutions.
Was pretty rushed when I got to that Q as I started with Section B, so didn't error check.

I've also gone ahead and done some worked solutions to the paper. I've noticed one or two things that I did differently from the one that's been already linked, so if it interests you feel free to look at mine too!

https://www.dropbox.com/s/5n036hqzbny7v6h/VCAA%202017%20Methods%20Exam%202%20Worked%20Solutions.pdf?dl=0

This exam's multiple choice section was easier than usual, but the extended response made up for it in some areas!

There are a couple of discrepancies with mine:
You have the correct answer for Q5, mine is incorrect, otherwise our MCQ answers are idenitcal.
In Q2c, you found where the derivative is zero, but we were asked to find where the rate of change is at its maximum.
Looks like you've commented on the other ones already

Given that the question was worth 1 mark, I would probably suggest that the domain won't be required, however, the assessor's decide the marking scheme, not the setters (i.e. the people who write the exams)

The equation of the tangent is defined by the point that it is tangential to, so you've tried to use the definition of the tangent to find a point on the tangent, which would most likely give you u=u or something similar.
The way I did it was to find the gradient of the tangent using the derivative function at x=u, then set this equal to the tangent defined by the right-angled triangle
where is the point

Seems like VCAA is deciding to change their game a bit. The E.Respose questions required a lot of brain power, compared to the previous years. I feel like they were trying testing how how far we understand the complexities of grapghs, rather than knowing the basics such as stationary points, asymptotes etc. of functions

imo they should have given us a heads up about the change (at methods PDs), b/C I expected the exam to to be similar to last years since the curriculum changed last year not this year, and after doing all those trial exams particular patterns of questions (from over the years) become embedded in our minds, and today's exam didn't really conform to that style.

I don't see any problems with this type of approach. It seems like you just applied standard results about maxima and minima from the study design to a function that happens to be the derivative of another function. The use of double derivatives tends to be more of an issue when students use them to classify stationary points, which doesn't seem to be what you did.

really depends on rank #1 in your cohort if they also did well than you could get a 49/50, and also depending on how many people full marked the first exam + got higher than 75/80 for the second, but you're definitely looking at a high score above 46 for sure!

With SAC scores of a high B+, rank 5-6 out of 9 in a relatively strong cohort, and 25/40 for exam one and possibly looking at around 35-40/80 in exam two would it be at all possible to get a study score about 25?

Relax bro they are good scores, you will defs get 31/32+ study score with 25/40 being a middle B+ and 35/80 being a High C+, or low B at worst
