Specialist Exam 2

[GeniDoi]

did any one find the acceleration or something in one of the questions to 3 decimal places to be something like 0.600, like the last two digits zeros.

I got a = 0.902? For the inclined plane question?

Same here

2014 was literally nothing compared to this years one lol

Didn't go bad but wasn't great, I found the mcq hard af though

that must have been it, dam I knew something wasn't right haha

You'd lose it You don't get any answer marks if you write a wrong answer
Probably

Nah I mean like I wrote 5pi/12 but that's it like I didn't write +-5pi/12 then say the negative one is invalid if that makes sense... Aw well ahha

And just realised I got the last question 4 part wrong because I typed in t=25 instead of 45.. How many would they take off for this, considering the mistake was typing it in my calculator wrong?

Out of curiosity, what do you guys think Spesh will scale by this year? I didn't think it was too bad (messed up Exam 1 big time though) but since a lot of people found it harder than previous years exam, do you think it will scale more? Unlikely right? Since it already scales so much

[bobisnotmyname]

so does anyone have a copy of the exam?

The difficulty of the exam doesn't change the scaling, it changes the mark required on the exam to achieve a raw certain study score. If the exam was more difficult it's possible you might have only needed high 60s/80 to get 40 raw (provided a similar score on exam 1) compared to the 72.5/80 for 2014.

I'm gonna give it the benefit of doubt and say it was slightly more difficult than last years, so it may drop to 70 or even 69, but I doubt it'll go much lower.

Should be the same as other years.
It won't scale past 55, that's absurd and 40 won't scale much past 51 because that's suggesting that 40 spesh is harder than 50 basically any other subject

I could be wrong, but I don't think scaling matters if it was a hard years exams or not, only if the people completing the subject go better in other classes. So probably the same scaling

I thought in 2013 the methods one scaled 8 and 2014 only 5, because 2013 was hard? Same with accounting (probs more, just the ones I know of)
Or is it just spesh that has a set scale? Makes sense cos 2014 piss easy exam still scaled 12 at 30/35

[yeahm8]

Does vcaa give working marks? Eg. The second last complex number question I used quad form and subbed the identity but stopped because I thought I wasn't on the right track. Any chance for a mark?

[TiffanyF01]

Thank you everyone, that makes so much sense, I didn't realise that difficulty would affect the A+ cut off and not the scaling, which makes sense and is also more fair
THANK YOU

I just quadratic formula'd it and the discriminant turned out to be 16cos(theta)^2 - 16. If you take a negative out you end up with sqrt(-16(1-cos(theta)^2))
= 4sqrt(-sin(theta)^2)
= 4sin(theta) * sqrt(-1)
= 4i*sin(theta).

For that one I just argued that the expression under the radical was negative, so negated that and stuck an i at the end
