    Hi

    Just a quick question regarding rounding down.

    I've had a potential divider question, and have calculated the current.

    now I've rounded that to 2sf for my answer but I still use my original 3sf answer in my calculations, according to the mark scheme they are incorrect in subsequent questions, the mark scheme is using the rounded result not the acctual.

    What is correct?

    Thanks

    I would always stick with the marking scheme but things may have changed. I would advise consulting your teacher.

      I agree with what soup said.
      The exam board will have guidelines on its website.

      Could you post the actual question and figures, it would then be easier to see what's going on.
      For example, why did you round to 2 sig figs? What data was given in the question? etc
