    Does anyone know why the C3 June 2013 grade boundaries are so low? Is it because it was a replacement paper? I don't know why that made such a big difference as the replacement wasn't too difficult.

    Idk I just thought that getting 64/75 and still getting full UMS was a bit crazy.

    I thought so too, but when I did the paper I only got 59/75. There were some really sneaky parts, like the function question.

    Their solution says 2b????
    (Original post by Zacken)
    The PDF clearly says \vec{BG} = 2b where are you seeing 3b from?

    Edit: ninja-ed.

    ugh I wrote this wrong.

    My solution is 3b. The answer in book and pdf says 2b.

    Ratio is 3:1, so the length of the entire thing is 3 (OG) and the length of OB is 1. Hence the length of BG is 2.

    No, the context of the paper changed, so it wasn't the standard one. Although was happy to get that tan x 1/3 40 question right first time :moon:

    https://www.youtube.com/channel/UCCg...v-Uw/playlists this guy is great if you prefer seeing an actual person on the screen with a whiteboard. Videos aren't necessarily specifically for Edexcel but it's pretty much all the same content wise

    I take it you are looking at the home C3 paper, not the R paper, as R stands for "regional" not "replacement".

    As you say, some people didn't like the function question, which requires you to read numbers off a graph, not plug them into a formula. Some complained that noone had ever told them that cos 50 and sin 40 were the same. And then the last question caused grief, as some candidates immediately assumed that they had to know something about mechanics "which isn't fair, because I don't do Mechanics" rather than carrying on reading and discovering that everything they needed to know was given in the question.

    Yeah I guess it was a bit 'different' for a C3 paper so I can see why people found it tough. It was a replacement paper though as the original one was withdrawn.

    Yes, this was the year that a courier couldn't find a packet of papers that they were supposed to deliver to a school in the Netherlands. Papers that that had already been written for future exams in M2 and M3, C3 and C4 and FP1 to 3 were hurriedly given final checks and printed.

    C3 June 2013 was a nice paper. They can make core maths interesting if they just want to - eg IAL C34 June 15.
