Additional Maths Discussion (Overall impression)
MR.BooMBastiC:
who on da earth takes add maths
divineobsidian:
i lost around 15 on the first and maybe 8 on the second kind of a a/a* borderline i think so im hoping for the best :) thanks to this board i didnt fail miserably like in the mocks ::)
saiki:
the paper was great... it was much easier compared to past papers... ;D ;D ;D ... im expecting A* ;D
saiki:
By the way, just wondrring, qs 12E prt 2
is 2/(e-1) the same as -2/(1-e)?? it is rite?? i got the second answer but others got the first one...
other than that, in p2, i could get all correct (i finished it in 1hr15min).... in p1 the graph was annoying... never noe if im correct or wrong, got k=9000 somefin and n=-1.205 or somefin...

IGCSEzindabad- if u lost 18 marks in p1, im very sorry 2 say u may not get A*, and depending on grade boundary not even an A :( cuz this was a VERY easy paper compared to past papers, so it may have a high grade threshold - admath has had threshold of 71/80 for A before.
oh for the answer wher u had 2 find n and k, n=-1.2 according to calculation, but they def hav a range, i got -1.22 from my graph. but thers a HUGE range for k because even if n value is diff by 0.01 percent it will hav a HUGE effect on the k value, cuz its log remember? so they have ranges for that just make sure u took the right values from ur graph, drew a sensible straight line and showd wher u got ur values from..
on the whole i thot both the papers were extremely easy, ther were no major matrix questions, sets were easy and no permutations only the typical combination question
