Is there 'e.c.f' in the titration question? I just somehow calculated the mean titre incorrectly. I gave my answer in 2 decimal places. Now, the problem is, that my every answer was in 4 decimal places or so. Will I get the marks for other parts if I have calculated the wrong average. Decimal places matter or not? And is there a range of answers in the graph question? They haven't stated a range in the marking schemes. Thanks.

If you write a little bit underneath the lines given for the answer, do they deduct marks for that?
