Hello Ms, my name is savia idres. I am a Yr 13 student in Iraq, Ms I have a question regarding past papers,I have problems with which value to use when using an answer from a previous question in a calculation. Do I use the rounded value or the calculator value? Especially when using either would result in different values. For example, in this question -Q1 - 9702/42/M/J/19: Ms for question C (i), my teacher said I would not get the mark for having gotten 6.5 x10^-11 instead of 6.4 x10^-11, even if I show my substitution clearly. And Ms one problem I come across is. It's really confusing that each past paper is different, sometimes they use rounded or calculator values and both give different values. What do I do then? How would I know which to use?
@Savia Idres you have to understand the fact that the ms is just for guidance again , small variations in answers will still be awarded by the examiner , i have experienced this before during AS where i saw how examiners actually correct the paper with official rules , but remember when another question asks you to use your value in the previous question (you may rounded it to 1.57 or 1.6) , you can use that value to work out the next answer there would be no problem , but if there is a question which just says calculate the next quantity , it's alright if you use the rounded off value in the previous question but you might lose a mark due to early rounding(it's rare but don't take the risk lol) , I recommend you use the calculator value ( the ms answer might be different) but the examiner will award you full marks so dw.
We need more teachers like you in this planet guys fr..
Would I lose marks if I had used the rounded value, when the mark scheme used the calculator value and gave me not the exact value? Or vice versa?
miss is this still in the syllabus?

For further calculations, use the calculator value
@@ayeshakhan8726 but there are cases when using the calculator value ends up with a different answer from the mark scheme
