Sitting my AS physics in oct/nov, I was going through some past papers and in the mark scheme the values in the working are rounded to 2 or 3 SF and the end answer ends up being different to me. I usually leave the values as it is during working and then round to 3SF at the end (i've been doing this in school internals and I havn't been penalised at all)
What does cambridge want? Does my working have to be exact to its mark scheme??
I am referring to question 1D in W11/23 btw, I get 5.833N for T1 but the mark scheme says 5.7...
Any help is appreciated, Pls give me a hand!
