1. On every past paper I've done, if there is no single option for 0 it is classed as wrong according to the mark schemes.

Oh, don't get me wrong. Im not saying having a single option for 0 is wrong because that's completely fine. I'm saying it's just as acceptable to include an option for 0 in a range.

Yes you are correct

4. Ohh okay, thanks for letting me know
5. I may be wrong, but wasn't the expand and simplify 2 marks and the simple factorisation only 1 mark?

Spoiler:
Show

Question 4. Simplify.
P2 x P5 = P7 (1 mark)

G6 ÷ G4 = G2 (1 mark)

(K3)2 = K6 (1 mark)

Expand and simplify 3(m+4) - 2(m+1) (1 mark)

10-5m

Factorise n2 - 7n (2 marks)

n(n-7)

6. for the circle and square areas, if i wrote 100 - 25pi in my working out clearly but put 75pi in the answer box, would I still drop a mark?

They're all correct.

3 mark question. 1 mark for area of a square and 1 for circle - I think

However It could be 1 mark for area of circle and square, 1 mark for 100-25pi and the final mark for 25(4-pi)

Since the official mark scheme isn't out we don't know. However I think it's the first option. So you'd only drop one mark.
9. Who do you think you are??? Running around the skies tearing marks apart?? Who do you think you are...

alright.

also for the rotation question, if i rotated it correctly but clockwise instead of anticlockwise would I get one of the marks?

Most likely no marks at all since it was only a 2 mark question IIRC.
13. No chance. An expand and simplify question would NEVER be one mark. It is two. And the factorising question is only 1 mark. I am 100% sure.

(Original post by 34908seikj)
They're all correct.
14. If you write T=5x+2y, you get 3 marks, with no working?

What if you write 100-25pi, then the next line write (100-25pi)/4, as I thought it was only one shaded bit we were trying to find?

they do 2 marks for correct answer? damn.

Haha n^2 - 7n can only be factorised as n(n-7) or I guess you could complete the square on it, however that would be ****ing pointless and incorrect.
17. 3(m+4)-2(m+1)=(3m+12)-2m-2= 3m-2m+12-2 = m+10

3(m+4)-2(m+1)=(3m+12)-2m-2= 3m-2m+12-2 = m+10
Wrong.

3(m+4)-2(4m-1) expanded is 3m+12-8m-2 = -5m+10

I don't understand your point. I know it can only be factorised in this way. It was only 1 mark, the original spec should be adjusted, as it was the expand and simplify was 2 marks, for expanding correctly, then simplifying.

You may get one mark, as if you rotated it 90 degrees and by the correct point, it is only the anti bit you got wrong.
