    I was just wondering what the go to decimal place or significant figure amount is, because I always seem to be just off when it comes to stuff like the equations of regression lines and in the mark scheme there doesn't seem to be any guidelines for what the markers leniency should be. Like I'm always off on the final equation because of a slight difference in my calculations because I might have rounded to 2 decimal places instead of 3.

    So I'm basically wondering will me being a decimal place off end up with me getting the rest of the question wrong or do they have a certain leniency? Also whats the advised sig. fig. and decimal place amount?
