Compared to past years, I thought it was quite time-consuming. Normally I finish in 1hr -1.5hr but I finished in 2hr today.
Bit harder than previous years but pretty good overall

I thought it was pretty easy.. Only question i had trouble with was the tax question 27b (do you minus medicare levy from the thingy?) and 29e - the one where he decides to pay an extra $250

No you add the Medicare levy because that is also a tax.
I had trouble with the last question as a read fuel to mean petrol in the last part so I had to redo it.

So did you add or subtract it from the value (it was 18000 odd from memory)?

Yeah I subtracted the levy, it said the levy was 1.5% or whatever from her taxable income. So idk I got confused not sure if i'm right.

The one where they repay an extra 250 a month you just add that value to M (in the annuity formula... I think the initial M was 2000 or so and then you simply added the 250) and figured out if it reached $300k in 20 years.

My answer was that it didn't.

How are you meant to do the interest on that loan thought, I was getting around 900k with compound interest formula (and I think FV annuity formula was around same) can that be right? I wrote that he wouldn't reach it anyway.

So I lost 3 marks for that last question because I over complicated it. And I lost 3 marks in MC already because I didn't read the question properly or worked it out wrong.
94/100 at best which is actually disappointing.

It has to be an annuity as he made constant repayments iirc. My value was like $285k or something so he was short about $15k.

Anyone else do the same or am I wrong? I'm probably wrong.

Hayley, 94/100 will probably scale to 9387878439787% dw. I feel like I got about 85% which will scale to low 90's imho depending on how my cohort goes.

My answer was that it didn't.
Did you use the first present value formula?

I used that formula and worked out the bracket part and got an answer. I then did 300,000 divided by ANSWER.

Then I multiplied that answer by 240 and got that it was somewhere in the $500,000s...

So I said he would be able to pay it off.

Am i wrong..
