    Short Answer Essentials

    To add to this, a person in a visual text is literally free marks. There is just so much you can talk about - gaze, gesturing, expression, posture, clothing, how characteristics of different people in the visual are the same or different and what this represents etc.

    Difficult induction question, or maybe I'm just missing something simple?

    I was experimenting with trying to make difficult questions for my own practice and then found that this seemed to work. But then I struggled to prove it lol.

    need edrolo account!!

    What subjects do you need it for? You should note that students with edrolo don't have access to all subjects, just the ones that they are enrolled in.

    Is there any point of doing an Economics degree if you can get into a Bachelor of Commerce?

    How much would I have to narrow this down in order to choose a degree/major? I haven't really thought about this in depth. I was thinking something analytical because I'm good with maths and data/statistics, but I also like the news and events side of economics.

    Is there any point of doing an Economics degree if you can get into a Bachelor of Commerce?

    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...

    Complex no.

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

    Complex no.

    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...

    What is a wordy hsc subject with least amount of extended response

    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.

    Complex Number Question

    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

    Cambridge exercises: are they unnecessarily challenging?

    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...

    Where can I see exemplar work, or examples of good essays?

    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...

    Can I get some help with questions?

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

    Can I get some help with questions?

    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.

    4u maths

    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?

    Raw mark for state rank in chem?

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

    I don't understand this

    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...
