    Here are my solutions to the Core 1 paper. Reasonably straight forward paper I thought.

    I think it will be about 62-63 for an A.


    I have also uploaded my solutions to the international paper which I thought was quite a bit harder. However I made 2 errors

    I think you've made two mistakes:

    On question 6D, the value of x2 is 1-k=1-1.5=-0.5

    So, x1+x2=1-0.5=0.5

    50*0.5=25, which I think is the right answer and not 75.

    On question 8C, the final range should be 2.8<x<3, not 0<x<3. I made that same mistake during the exam

    Thank you very much for uploading this mark scheme.

    I have one little question, in Q7 i made a silly mistake, and made 21/2 simplify to 11.5 (instead of 10.5), so i ended up with S21=9200 (instead of 8400), but i did the next part correctly and got 18600. Then i added the two giving me 27800 instead of 27000. How many marks do you think i will lose for this out of 5? will is get any ECF marks?

    For the phone question I used N as 24 but used the right method in part B how many would I gain out of 7 on that question? Also for the co-ordinates of intersection of L1 and L2 I only got 1 co-ordinate correct?

    Well it went ok, I think I only dropped 5/6 marks depending on what marks are dropped for.

    For question 6b, did we have to solve the silmutaneous equations by elimination? I did it by substitution and ended up with the same answer, I didn't really consider any other methods since I was a bit stressed I only had about 5 lines to do the working out for part a and b

    On the arithmetic sequence question I got the first part right and got 4800 for 21 terms, but stupidly wrote 600x31=1800 and hence ended up with 10800 as the total. How many marks would I lose on this question? Got everything else right though Just really wanted 100 UMS for once.

    This was a relief! Thank you for putting these up! I think I've just lost marks due to silly mistakes. Ahh. It was a nice paper.

    yh it was such a silly mistake. I matched all of Arsey's other answers, so this might have cost me the 100UMS
