Maths exam IGCSE - HIGHER TIER - PAPER 3H AND PAPER 4H POST DISCUSSION.

For the question with working out the area of ABCD, I STUPIDLY put the area of the right handed triangle as the answer... how many marks would I lose? I'm estimating that I'd lose about 2 marks? With that in mind, I've got 92% in 3H since I pretty much lost 6 marks in Q18.
EDIT: The estimate for the interquartile range - I didn't put a whole number. Do I lose marks for that?

Dude do you by chance have the 4H paper?
and tell me how you got this 3h paper!!

seriously where the hell did you get this paper from??!

Hi guys, I am about to download the paper do it with workings and right answers and I will then upload it for everyone to see. I will also estimate grade boundaries according to how hard this was compared to what I did last year. Give me a little bit of time then both with be up

hello anyone?

for the pentagon question would i still get full marks because i did a different method to find n=10:

4x360= 1440
1440/180 +2 = 10

so for probability one, i should have done 3-1, 1-3 and 2-2 twice!? damn! what was the answer? I got 3/20- so annoying as couldnt decide if i should do 2-2 twice or not!

I think for a you will get FULL MARKS

HEY , does anyone know how many marks the polygon question was? and the angle question? and if any one gets the marking scheme and actual paper can you send it to my inbox? and is anyone sitting for biology on tuesday? omg im so worried...is there a confirmed boundary? thank uu for any thing that you can send to me.

PLEASE HELP!!

for the polygon question the followin is my answer(method is wrong)

1 pentagon=5 sides
2 pentagons= 10 sides
therefore n=10


How many marks would i get??

For question 19 (Triangle within sector) the area of the triangle can be found simply by 0.5*A*B*sin(c) formular.

Thanks for the working . Your sure for the 5th question you get 2 marks by simply writing down the 3 numbers by trial and error?

Maybe 4H will be easier and raises the grade boundaries

From my centre.

No, stop freaking out. 90% is way beyond an A* get off this thread.

ye you needed to do 2-2 twice
