I have a passion for economics and am quite certain that I will do well in it at uni. I'm planning on majoring in econometrics and maybe some other economics major, which I think I can do in a Bcom or Beco. I'm predicting that I will get an ATAR much higher than the cutoff for either, so if I'm...

Where do they publish examples of Band 5/6 Work? Do you have a link for other subjects' exams?

Who develops and marks these exams? Is it only select moderators or some other BOS users?

That's true, its' edited now. Interestingly, by making the same mistake twice I still got the correct solution lol.

Let z = a + ib It follows that \overline{z} = a - ib If z\overline{z} = 5 then a^2 + b^2 = 5 If \frac{z}{\overline{z}} = 0.2(3+4i) then \frac{a^2 + 2abi - b^2}{a^2 + b^2} = 0.2(3+4i) (by multiplying using conjugates) =\frac{a^2 + 2abi - b^2}{5} So a^2 + 2abi - b^2 = 3 + 4i Finally...

The old naming was better because it implies that IST (Information Software and Technology) correlates IPT (Information Processes and Technology) and SDD (Software Design and Development) These new names are... ok I guess.

15. Let z = a +ib \overline{z} = a-ib a^2 + 2abi - b^2 = a^2 - 2abi - b^2 4abi = 0 By null factor law, a = 0 or b = 0 If a = 0, z = bi and is purely imaginary If b = 0, z = a and is purely real

I would reccommend Cambridge to MIF, it has more nuanced examples and better practice for harder questions. Looking at MIF, my opinion is that it's a waste of time to consistently repeat the exact same skill for 10 questions. If you want a good middle ground between easy explanations and...

Is there anywhere online I can find examples of very high-quality work to guide me in improving my understanding? Something like Arc NESA but with recent examples and new syllabus content. In particular I'm looking for English Advanced and Economics essays, does NESA still publish scanned exam...

Your contributions are definitely appreciated and valuable. I definitely don't see it as a competition, just making humour of the situation lol.

I was rushing for time to not get beaten by @CM_Tutor lol. Embarassing to say it took me a few minutes to type it out in TEX, and it would've been awkward to get ninja'd by CM.

({14 - 2x\over\pi})^2 \pi (ignoring the +x^2) (({2\over\pi}) (7-x))^2 \pi ({2\over\pi})^2 (7-x)^2 \pi {4\pi\over\pi^2}(7-x)^2 {4\over\pi}(7-x)^2

Is it worth explicitly studying for 2u in that case at all? I heard of someone that ranked 1st in ext 1 and ext 2 at a school, then got mid-30s in adv. Do you have to care about your 2u internal rank if you're certain you will do well in 4u?

State rank might look attractive for scholarships and if you want to tutor at a prestigious tutoring centre.

Essentially yes, this is the process known as scaling that everyone talks about. It compensates for the literal fact that it is harder to score raw marks in extension 1 compared to a lot of other subjects, so an 80 in each subject has a different contribution to your atar depending on the...

From the graph, we get that there is a double root at x = 2 Then, use an appropriate method such as sums and products of roots or polynomial division (let me know if you need me to demonstrate this) to find the other solution at A. You would get the factor (2x+1) or solution x = -1/2 Then...

Is it true that it is recommended to do a related text that is a different medium to the prescribed text? I've heard that it allows for more technical analysis.

b) There is Q grams of salt in the tank, and the tank itself has 1000 litres Therefore, each litre has (Q/1000)gms of salt per litre of water.

The saying is 'broken record', but broken recorder sounds funny if you imagine a year 8 kid trying to play a literal broken recorder. I guess the saying still works because they both mean something that sounds irritating.

Consider the fact that when a function is squared, each point on the function is squared vertically, since the y-axis is the output of a function. For every point (x,y) the new point is (x,\sqrt{y}), where y≥0 If a HA is at y=3 for example, in the root function it is at the square root of...
