# Edexcel IGCSE Mathematics A - Paper 3H - 2016 - Unofficial Mark Scheme watch

1. (Original post by WhiteX)
when the mark scheme will be available ?
I don't know but hopefully soon!

80%o for a* is so high though surely???

I agree, it was a slightly unfair paper due to the amount of 5/6 markers - it may be lower but I don't believe it will be too much lower. I'm predicting it'll be about 78-80.

Me being me,
I put -3x+4y=-19 which is still right but hoping for the oe to be on the mark scheme!
Same here mate. Pretty sure that'll be full marks, would be super harsh if that wasnt on the mark scheme

thats how they filter the best from the rest though
i am the rest
5. Grade boundaries anyone? So wanted an A but messed up all the questions with 4/5/6 marks
6. (Original post by WhiteX)
it was 5 mark i divided it to 3 triangles i did the first one and i didnt do the others so i might get 1 mark of 0
aa thank u!!good luck
7. nah sorry mate if it's only a 1 mark question then you can only get 1 or 0 marks but if it's put of 2 or more, you certainly will get marks for working

what about if i only wrote y=3/4x-4.5 with corret working out but i didnt re arrange it and times it by 4

how many mark will i get out 4 or 5 i dont remember the total
9. How many marks was question about spheres???

that would be -1 or 2 at most because you got the base equation right

it was 6 mark q not 5 so if you did the area of firt triangle you should get 2 i think

ok was this q 5 or 4 mark ?

5 marks
16. Guys what was question 10? im afraid i missed it because i dont remember any answer of 10.7...

You were given 4.5cm which you have to convert to MM via the multiplication of 10, giving you 45cm.
The upper bound value of 45 is 45.5, hence you have 45.5MM
Divide this by your MM value, which was 3. This needs to be a lower bound to produce a maximum value and so you should divide by 2.5MM ( question stated 3MM to nearest MILIMETRE).
This would have given you 18
Thats wrong, finding the upper bound and lower bound is correct but you do not just divide 45.5 by 2.5... that wouldn't be a question 20 more like a question 5. You have to find the upper bound volume of the cube and then divide that by the lower bound volume of the sphere. which is 45.5 cubed divided by 4 over 3 pi 2.5 cubed. which gives you 1439 rounded to the nearest whole number.

OHH YEH it was the triangle... nvm I didnot miss it
19. (Original post by _Xenon_)
Thanks. Do you remember how many questions there were?
25 questions overall. The tree diagram one was 0.04 or 4%!
