Is Q8 even in syllabus? Knowing that exp(x+iy) = exp(x)exp(iy) surely isnt in the scope of 4u. I’m sure most 4u students have discovered exp(z)^n = exp(nz) doesn’t always hold true for non integers (hence demoivres only being true for integers) so to expect them to know the addition of...
If you pay for raw mark they only tell you the mark you got for each q. it looks like a table.
If you pay more, they'll send you your exam responses, it looks like this (but obviously with every question
You do not get feedback on your response ever. Markers don't ever write it during the...
scaling is just for atar. Alignment is for deciding your hsc marks (essentially its how they make sure a band 6 in say english is just as difficult to get each year regardless of how hard the paper is). so like a 70 in 4u last year aligned to a 93 hsc mark and that scaled to a contribution of...
yep, though you can get a good ballpark if you check what the alignment was like on rawmarks.info. I only paid for modern. 85.5 raw went to 93 HSC mark.
Its after alignment (not scaling, though the terms are often used mistakingly interchangably) has occured. if you want raw you pay nesa 29$ and they give you it
Universal 4u experience. In all seriousness, still look at the qs! You might be surprised that some of the questions are way simpler than you'd think. I got more marks in q16 than in q15 in my year 💀
What the word "plane" even means is is not in syllabus, so unless its heavily scaffolded your suggestion that they derive the cartesian equation of the plane through the point normal form is silly. Unless they explicitly give you the formula n.(x-a) = 0 lmao.
