As I said in my first post, I'm not going to make any predictions.

in question 9, a) i found the area of rectangles correct but the rest is wrong, how much would i get for it?
and in bii) i didnt convert the litres and applied the formula v= pi x r x l .. how much would i get for it?

hm 185-190, thats an A* right
and when do we get out marks?
And do they show out raw marks, precentile marks out of whole world , or letter grade

9ai. If you added 2*(your hexagon area) to the correct rectangles area then I think you'll get 2 marks.

9bii. I'm really not sure here. I was surprised it was a 5 mark question so I don't know how the marks will be given.

also does writing gradient as fraction give marks?
and would 2.7 e in the range of accetpable values?

Writing as a fraction should be OK. 2.7 won't be in the allowed range.

I would guess you'll lose 1 but it could be 2.

I think this will be a very common error.

Typo.

You'll lose 1 mark for 19 and I'd need to see all your working to know how many you would get for the percentage question.

ALRIGHT THANKS. BUT SINCE THIS YEARS PAPER(MATH 42) WAS HARD COMPARED TO THE OTHER YEAR WILL THE GT BE LESS

 

[Fayadh Ahmed]

I got 177/200 Hopefully I'll get an A*

 

[alamgir]

about finding the profit, Sir i did all the working correct showing the correct answer in the working but i wrote 84 instead of 184 in final answer line but i have done all the working as done in the paper 4 post by you.
