    So I've been doing loads of S1 past papers today.. and I've noticed that on the mark schemes some answers are underlined and written in bold with 'awrt' next to them..
    I know that 'awrt' means answer rounded to, but i keep getting answers wrong bc i havent rounded them/left them as 2sf/1dp/whatever they're looking for, but most questions don't specify which degree of accuracy they need answers to be in.....so how am i supposed to know what to do..

    If the question doesn't specify that the answer has to be in say, 1dp, but the answer you got was exactly 2dp, would you be marked down for leaving the answer unrounded..??

    thank you! so nervous for S1 tomorrow

    I always write all values down, and then IF THEY HAVEN'T SPECIFIED then round to 3SF. I was making a lot of mistakes because i wasn't carrying out every specific value throughout the question. i.e. don't round any value up when working within the question; only round up at the end.
