Um it's definitely harder than most subjects because it requires a deep understanding of the content and is more than just rote learning and writing down the answer. In saying that, the maths is mindblowingly easy compared to 4unit maths.

to calculate time of flight use deta y = u(y)t +0.5a(y)t^2 take the cliff as the origin (i.e. delta y = 0), so if the height of the cliff is 100m then when it lands 100m below, delta y = -100 and plug u in. Then you get a quadratic equation, use quadratic formula to calculate t, disregard t as...

Also regarding AAS, only talk about specific wavelengths of light being ABSORBED (and definitely not re-emitted) by the atomised sample. This is because AAS works by the principle of comparing the amount of light absorbed by the sample (the more absorbed the higher the concentration) in...

you add of course

precisely, 75/100 raw mark aligns to a 90 hsc mark, which constitutes a band 6

can you just get a state rank

this is like the super all rounders award haha

can you get on msn once in a while? Also yeah official is right with the raw marks

96+ hsc mark

I did the same

This is wrong. The tariff raises the price of the good unconditionally, the producer does not obtain the revenue then pay it off, it is an additional price levied onto the cost of the good. Before the tariff, the revenue generated is 300 x $10 = $3000. I think we can all agree on that. After the...

I found the exam easy - the first choice of essay questions were gifts, but the second one was pretty difficult.
