rounding / sig figs

do the take marks off if you leave decimal places when they ask for it to be rounded to the nearest whole / to -- significant figures??
I didn't have to time review any answers and am worried I have not rounded to what the question asked.

Thanks!

I think they would if they specifically ask you for a figure
I think what you're referring to is this question in core

You needed to have two sig figs for both values as the question is 3 marks. Probably 2 for correct answers, one for correct sig figs. Or the other way round. Otherwise you can still obtain 2/3 or 1/3 if you didn't :)

I also left the cents of the last question for finance (lump sum), rather than rounding it to the nearest dollar 😩

No longer 1 mark max.

Pages are scanned and sent to examiners at random, so your one exam could be marked by 7 individual examiners - each could take a mark off for rounding issues.

No-one is checking overall how many marks lost to rounding.  Could have a significant impact on results.
