S1 Calculations

If i were to round the value of an answer, and from that the answers of the next few questions are off what they should be, how many marks could i lose, its down to a matter of +-0.003, would they penalise me for this and if so how many marks would i lose for something which seems a bit harsh

Probably not? Since I think you're recommended to round it to 3sf unless otherwise mentioned. I think the best thing is to try not to round it until giving the final answer.

Just doing some past papers and in the mark scheme they seem to be very precise with their answers, not sure if the examiner will follow it precisely though, i really do not expect them to be THAT harsh but you can never be to careful
