I just has a query about the last question on the Paper 6 IGCSE Physics paper as I am unsure where to find the value of T = 2.0 on the graph . Did you have to intercept the Y axis at 2? Or am I wrong.
I assume you will get 2/3 marks for showing working seeing as most mark schemes tend to give more credit for working than actual answer
Yes i realised in the last minute and my working line was wavy i put 0.9 but i believe the answer was 0.99 so i should get 2/3 - do you know approximate grade boundaries for an a in this paper (the highest grade u can get per paper) ?

Ur wrong... Its Tsquared... Its at 4 and its 0.95-099
So i got the voltage wrong for some reason... It asked you to then find the resistance, then to find the ratio... As my voltage was wrong so was my resistance and ratio but would i get carry on marks as i showed the correct working

Were u meant to give that answer as a retio - and you would have got error carried forewards marks
Guys for the question on the first page... i just found out that x=1.4 and y=2.6. I did it 1.9 and 2.1 cm. And so i used these values for the rest of the question. I could have sworn i measured them correctly. Anyway please tell me that i can get any error carried forward marks for that question. it was worth around 7 marks.
So how many marks do i lose for incorrect measurements for x and y. I did the rest of the question correctly but with the incorrect measurements. The whole question was worth 7 marks?

Ye i got the voltage wrong of the reading so my ration and resistance was wrong but we probs get a carry onerror if you showed your correct working and so you dont lose as many marks
