Far out, I was sure 2 was C, but I just looked it up. Damn 2011 census. I never get those demographics questions wrong. Agreed with 9 and 10.

Question 2 I thought was C, not B. Question 9 I got D, but I wasn't sure. Question 10 I thought it was A, not sure. We got the rest the same.

I don't know about everyone else but my class wasn't very prepared for the first extended response. I had prepared a Judaism response but decided to do a Christianity one on Pope John 23. Ended up alright, I think. Other than that, I thought multiple choice was easy, 5-markers were alright and...

Nah, I'm sure it's B. Measure it - it's exactly half way between 400 and 550.

Oh well. I got it wrong anyway (pretty sure). What calculation did people use for it. I thought it was 135 metres down and just over 3km across?

Really? Would that mean any negative gradient is wrong? I don't think I've got it right anyway. Thanks for the explanation though.

I do not see how it cannot be a negative gradient. Call me stubborn, but the first height is higher than the second height, so it has to be negative.

No, that's not the rise. It's exactly the same as if it was graphed, like in maths. If the y-axis (height, in this case) is 135 and goes down to 50, the gradient is negative, because the height is reduced, as the x-axis (run) is increased.

I'm not saying my answer is right (I never get these ones right) but gradients can be negative. It started at 185 metres high (the mountain) and goes down to 50 metres high (the lighthouse), correct? So, the rise is -135.

How could it be 27.7? That means it would go 27.7 metres up for every metre across? I'm not sure if I'm right but I got -0.0405 (I think). It had to be negative because it was going downhill and I thought the calculation was -135 (rise) divided by 3333 metres (run).

You might be right. The thing which swayed me from that is because I thought world cities aren't 'Regional' hubs, they're world hubs..if that makes sense. I'm not sure. I didn't think Bangkok was a world city in the first place but I knew it had more than 8 million.

Yeah, I wrote about different income areas in London and made up some bullshit for the linkages. I wrote my multiple choice answers in the other thread if you wanna compare them.

Only two problems (I think): 1. What did people write for the social structure of a developed city? 2. Can someone explain what exactly a linkage is?

I'm pretty confident I might have gotten 20/20: 1. D 2. A 3. A 4. B 5. C 6. C 7. C 8. D 9. B 10. D 11. C 12. D 13. B 14. B 15. A 16. C 17. B (might be C) 18. B 19. B (Crap! I think it's actually C) 20. B

I think I got 6c/a for 28b. 29d.i. is just 5% of her monthly income, so 5% of 81000/12.

It's weird: It's like half the students (including me) are saying it was easy and the other half are saying it was hard (and I'm not normally very good at maths).

But this doesn't take into account the part of the perimeter which has been created. You still need to add two lots of the radius, as there are lines leading into the circle; it isn't just empty space.

Quite sure you got the perimeter question wrong. I think you did 230/360*pi*13 but then you have to add two lots of 13 because that previous calculation only does the circular part of the perimeter.

Just checked the syllabus. Under one point, it says "sketching 3D solids using isometric paper and vanishing points". Has anyone actually done this in *general maths* class and not in an arts class?

Yeah, I think you're actually right. I got confused because I remember seeing a similar question which was "One is president and one is vice-president" but that's different because the order does matter.
