Hi everyone,
I am planning to complete VCAA methods exams starting from the 2006 exam. I am aware that there has been course changes so does anyone have a list of irrelevant questions (questions that aren't in current study design) so I can cross them off my papers? Would appreciate any help
Thanks

Hi,
a) One topic that is definitely NO longer included is the transition matrices (associated with discrete random variables). This topic always came in the Test 2, rarely in the multiple choices test (see Problem 10 in 2011 and Problem 8 in 2013), most often in the next Test (for example, Problem 2b in 2006; Problems 1b iii and iv in 2008; Problem 3g in 2009; Problems 2c and 2d ii in 2010; Problem 3b ii in 2012; Problem 4g in 2014).
b) While it is not explicitly excluded from the current curriculum, solving the system of three linear equation has not been seen after 2010.
c) To be on the safe side, check the latest curriculum: https://www.vcaa.vic.edu.au/Documents/vce/mathematics/2016MathematicsSD.pdf.
Hope this helps!

Hi,
Some additional information:
a) As for the systems of three linear equations, they came three times. In two cases, the equations had to expressed using matrices (multiple choice tests in 2006 - Problem 4, and in 2010 - Problem 5). This topic is no longer included in the curriculum. The only other occurrence was in the second part of Test 2 in 2009 (Problems 2a i and 2a ii). The solution could be found in a pedestrian way, and it is not impossible for this type of a problem to come up again.
b) As for the problems involving absolute values, I have not seen them after 2015. The current curriculum covers 2016-2020, and does not mention the absolute values explicitly. However, since students know what the absolute value is about, it is not illegal for the problems involving sketching or translating a function containing absolute values to pop up again in 2019.
c) In the past, i.e. before 2016, the tricky problems involving absolute values could be classified as follows:
(i) Determining which of the statements about the function is true or false: the multiple choice tests in 2007 (Problem 8), 2008 (Problem 21), 2009 (Problem 14), 2010 (Problem 18), 2011 (Problem 16), 2012 (Problem 22), 2015 (Problem 18).
(ii) Solving equations as in the multiple choice test in 2006 (Problem 11), the second part of Test 2 in 2006 (Problem 1d), multiple choice test in 2009 (Problem 20).
(iii) Finding minimum and maximum, but without having to differentiate - the second part of Test 2 in 2006 (Problem 1a ii), and the multiple choice test in 2007 (Problems 6 and 14).
(iv) Really tricky problems involving differentiation - the second part of Test 2 in 2007 (Problem 3c) and 2009 (Problem 1e).
(v) Given that the formula for the differentiation of the absolute values of functions is no longer in the textbooks, you can give a miss to (iv), and on the balance of probabilities, the cases (i-iii) you can check out only if you have time.
Cheers, and please let me know if you find mistake in the text above, so it can be corrected immediately.

Some bits of additional information. If one is really pressed for time just before Test 1:
1) From 2006 onwards, problems with binomial distribution have popped up in Test 2 only; and
2) Only 7 out of the total of 42 problems involving transformation have popped up in Test 1.
There is no guarantee that these problems will not come in Test 1 this year, but on the balance of probabilities you can skip them if you are really desperate, and prepare them before Test 2.
