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

1. i got 0
2. (Original post by Emilyros)
I got t=2 for finding the acceleration in the differentiation question, anyone else??
Yes that's right

for the probability you had to do all possible orders for picking numbers that total six, there was six possibilitieseach one had a chance of 1/21 so you had to add all 6
Yes but there was also the probability of picking three 2s which would equal 6 so you had to add that probability to 6/21 to get the final answer of 25/84.

Didn't say 4.5 cm was to the nearest CM that was for the MM value, so it definitely gave 45.5mm
It was to nearest half cm though so 4.75 cm is more accurate?

so I might not lose all the marks? Overall, did you find this paper easy/hard ?
pretty easy think i lost about 6 marks altogether and yeah you proably only dropped one mark on that as the right answer is usually only worth one

i got 0
if you differentiated twice you would get 12t +24 =0 which you rearrance and get t=2

Yes I know. That GCSETANK guy doesn't know what he's talking about so don't listen to him

youll probably only lose 1 or 2 on that question if you showed working
11. K<(or equal to) 2.5
And the greatest number k could = was 2

The gradient was 4/3 so y=4/3x-1

The person got 3,100 rupees

did you have to differentiate it twice for the first marks?
14. What do you need for UMS 100?
16. (Original post by izak)
was the percentage added on to the original percentage?
17. I got 1439 for the he cube and sphere one... Loads of other people did too?
18. (Original post by 5566677)
was the percentage added on to the original percentage?
1000 + 2100 = 3100 so 3100/6000 x 100 = 52%
19. before exam: can't wait for that A, maybe even an A*, team spirit, woo, lets do this, edexcel can't stop me now, im a mathematician
after exam: please say I got at least a U
