[Official Thread] OCR MEI AS Mathematics 2016 (C1, C2 & S1)

how many sig figs are you supposed to round to in S1? Mark scheme uses from 2 to 5 it seems random...
also would you get marked down for using too many?

3 to 4 significant figures should be good - anything above that or below that and they'd dock you marks :frown:

- how are you finding revision going for maths in general?

okay ill stick to that. I found this "Discretion must also be exercised in the case of small variations in the degree of accuracy to which an answer is given. For example, if 3 significant figures are expected (either because of an explicit instruction or because the general context of a problem demands it) but only 2 are given, loss of an accuracy ("A") mark is likely to be appropriate; but if 4 significant figures are given, this should not normally be penalised"

so it seems like 3 to 4 in general and then always use 4 dp for binomial probability stuff.
I was bricking it earlier but not too worried now. C1 is dialled. just S1 that can be tricky.

Honestly need to do so well in C1 and S1 because i just know I'm gonna fail C2 ahaha.
Got any predictions for section B of C1? - or do you think it'll be the normal graphs and circles etc

If you look at all the OCR MEI papers, they also seem to repeat and follow the same trend in all papers but they just word the questions differently. So there probably will be graph and circle questions and what normally comes up like binomial expansions etc

Tbh, I think practice is best for revision, just keep doing past papers. And go over things you don't understand. That's what I do anyway.

Ok thanks

Is it just me or have MEI grade boundaries have been getting higher and higher each year? Last year you needed 63 for an A and 58 for just a B!

tb to 2010 when it was like 52 for an A peak times
But the papers back then were much harder, last years paper was relatively easy so Im thinking we're gonna get a hard paper this year :frown:

Any predictions? Do you think one of these questions will come up they usually come up if the exam is hard: Screenshot 2016-05-16 at 18.43.15.png
