Further Maths (Exam 1): Discussion, Questions & Potential Solutions

Yes, though the starting statement says Vn is value after n years,  Q.18 says 'Between the SECOND and THIRD years, the increase in the value of this investment is closest to'
So, Wouldn't the value after 1 year be the value in the second year which is V1?

That's how I interpreted the question :
since Vn is the value after n years, thus :
V0 = after 0 year ( present value )
V1 = after 1 year
V2 = after 2 years
V3 = after 3 years
we can simply read Vn is ( V after n )

V0 = after 0 year ( present value ) - which also means first year
V1 = after 1 year - second year
V2 = after 2 yearsthird year
V3 = after 3 years

Ali kfp is correct, however, the amount of ambiguity and misleading to this question

This exam was a disaster 
*sigh*
Anyways can anyone pls explain q13 and 19 from core

[Lear]

I’m rank 1 in my cohort with a 100% SAC average. But I lost 3 marks in Exam 1. If I get 100% in exam 2, is it still possible for me to get a 48-49?

I’ve heard some people saying they dropped 3 marks and got a 50

Naw losing 3 marks for a 50 is a stretch, especially on exam 1 as each mark on exam 1 is worth more than each mark on exam 2 in terms of your study score (both exams contribute 33%)

V0 = after 0 year ( present value ) - which also means first year
V1 = after 1 year - second year
V2 = after 2 yearsthird year
V3 = after 3 years

Nope V0 is always considered the initial value and V1 would be the value after a year has passed. Therefore V1 is the first year. It has been this way for pretty much all past VCAA exams (couldn't find an exception)

how do we do q19 and 23

[Lear]

how do we do q19 and 23

19–> Find effective interest rate for each and select option with lowest

23–> Find interest rate PER ANNUM for payments before payment 28 and payments after 28 by dividing the interest paid by the previous balance of the loan. Then find the difference

Does the results of the rest of the state impact my study score? If I did better than majority what affects will that have on my results?

Sorry, I’m in year 10 and this is my first time doing a 3&4

Anyone got the correct answers?

Your study score is effectively your ranking in the subject within the state. If everyone does really well it can be tough to get a high ranking and by extension study score. On the other hand, if everyone found the exam extremely difficult you can get a high ranking without doing extremely well and thus have a higher study score.

In terms of this year's exam 1 i'd say it was pretty standard and am therefore expecting A+ cut off to be at 37/40 and  A to be 34-35/40

From discussions with others and people on this page I'm pretty sure everyone found this exam harder than previous years. Does this mean the cut off to A+ may be lowered to a 35 -36? or does it stay the same regardless of the difficulty?

V0 = after 0 year ( present value ) - which also means first year
V1 = after 1 year - second year
V2 = after 2 yearsthird year
V3 = after 3 years

:/ I did the same thing! I get so confused with those type of questions because i never know if i should consider v0 as the first year or not!

Difficulty really varies according to who you talk to. Ultimately no one can really tell how ‘hard’ it was by sampling 50 or even 100 people.
If this was indeed harder than previous years the A+ could drop to 35-36 but I, personally, am pretty sceptical about it.

another question - If the marks available is 2 but all you have to do is chuck the values in the calculator, do we still get the 2 marks just for putting in the final answer, or does it require showing how you calculated it?
 For example you put the values in the financial solver and you get an answer and then use that answer to calculate the final answer
