    The Official Maths Threshold Discussion.

    I'm going to guess that the A* boundary is between 172-178/200.

    Paper 42 (13th May) - Full Solutions

    That sounds like a high B to me (maybe a low A if you're lucky :))

    Apparently if you calculated the minor mark you will probably lose 2 or 3 marks (see page 1 of this thread, post #11)

    Paper 42 (13th May) - Full Solutions

    n = 20 is correct. If you look, the triangle number is shown by the P value on the left of a triangle, so Pn-1 = the number of triangles = 19, so n= 20 (if that makes sense)

    (2) is a 1 x 1 matrix.

    You don't lose a mark for putting 3x + 9 (this question was raised earlier in the thread)

    Another question, for the water flow question, how many marks would I get if I put 1744? (Instead of 1740)

    Paper 42 (13th May) - Full Solutions

    Was it the 39*4 arc question? Nevertheless 199/200 is brilliant - I've made a couple stupid mistakes myself (like Q2 where I put (5 -8) instead of (-5 8) as a column vector, and in the fertiliser question where I added 4 instead of taking away 4. There are some questions I don't remember my...

    You can celebrate for being the only person I've seen so far to get anywhere near full marks :)

    For the last matrices question, my final answer was left at: 1(3 -4) 2(-1 2) (i.e. Half * 3, -4, -1, 2) Would that be an acceptable answer?

    I don't think so. The question asked for the integer values so you would lose 1 mark (previous past papers have done the same)

    HARDEST MATH PAPER IN THE HISTORY OF IGCSE 0580 MATH 42 DISCUSSION

    Seems to be a lot of disagreement on the last answer :p I'll put in my vote for n=20 (that's what I got)

    HARDEST MATH PAPER IN THE HISTORY OF IGCSE 0580 MATH 42 DISCUSSION

    You multiply by 4. The arc AC has 2 triangles there: AOB and BOC. The angle MOB = 39, which makes up for a half of ONE OF THE TRIANGLES. Which means there are 3 other halves left to account for. Therefore the angle AOC = 39*4. (360-39*4 = 204 ---- (204/360)*2(8.5)*pi = 30.264 = 30.3 (3...
