    Whenever i attempt a question involving normal tables i usually get a slightly deviant reading from tables compared to the CT 3 core reading notes:( , why? :confused:

    make sure you're interpolating correctly and not rounding along the way.

    Absolutely!

    You will lose the answer mark if you don't.

    That's OK - thought the CT1 examiners are more relaxed about this...
