Mr M's Edexcel GCSE Linear 1380 Higher Tier Paper 3 Answers June 2011

OP

Is this paper marked on raw or UMS marks? I think I got 93+ or higher so that's probably an A* in raw marks but are UMS higher because some of my friends are worrying about their marks.

just forget about ums

Hey, Mr M.
Do you know how many marks I would get for the hemisphere question if I wrote:

surface area of hemisphere= 2Pr^2 + Pr^2
= 2Px^2 + Px^2
Surface area of cone= Prl (hyp) + Pr^2
= Pxl + Px^2

Therefore: 2Px^2 + Px^2 = Pxl + Px^2
(- Px^2 from BS) 2Px^2 = Pxl

Pythagoras: A^2 = b^2+ c^2

Then I somehow square rooted both sides and ended up with root 2 somehow. I know I got the answer wrong but by using Pythag and writing the formulaes how many marks would I get out of 5?
Thanks!

Thank you so much once again for such an accurate and detailed mark scheme and for answering all of my numerous questions - I really cannot thank you enough! :biggrin:

I think I achieved 84 marks/100. Will this be enough for an A* Mr M? I am really worried! :frown:
