Maybe, i also felt that i might have got the wrong answer on that one
I thought that was quite difficult

Got pretty much the same as you for most there! Although 6ii) I got 16.1% and 6)v I got 20% as did a few other people in my class... I wonder if they give a range of possible values as an answer for those who use the histogram to get the answer the reading might be different?

All in all, not too bad of a paper, section B was easier than section A in my opinion... I reckon around 61/62 for an A

I got this too
Well guess who failed S1 :frown:
is it me or was the histogram very difficult to draw because of the scales they gave you? mine was very cramped
Does it matter that I didn't put mean and sd to 2dp even though it was money
Exam was quite easy. Hopefully bring up my terrible C1 result. :smile:

You may lose an answer mark depending on how cruel the mark scheme is and how many marks the question was worth!
Did anyone get 1/60 for two answers in a row I think it was on the question about the runners

Yes it was 1/60th for two in a row, then 1/10th for the final answer

Nice I got the same. Always feel a bit insecure getting two questions with the same answer
