I posted hard GCSE questions in a thread around Xmas of 2014 in maths Exams
3. This 6 mark question came up in my GCSE exam and I quite enjoyed it.

Integers and are such that . Find the possible values of and the corresponding values of .
4. Here's one I've just made up, TeeEm style:

A sphere of radius 1 is placed on top of a sphere of radius 2 so that the line joining their centres is vertical. Find the radius of the base of the smallest right circular cone in which they will fit, with both spheres in contact with the cone.

I have also made one but I need to type it
6. Here is one I just made
(I got the idea a few days back when I was helping somebody)

In fact I think this is hard enough to go into one of my IYGB Special Papers (calculator versions)

Haven't got the time yet as I have cadets... however when I come back I am going to steam roll this question until I get the answer!! Spent 10 minutes on it and it makes my brain shrivel.

if you are a GCSE student this will hurt ...
I dare say most A level students will be brought to their knees by it.

All the best!

does north east mean a bearing of 045 or does north east mean a bearing in the range 000 to 090?

these terms are very specific
13. I may have posted this before but this is one of the hardest I've seen, mainly because of the amount of work you had to do for one question. It's from an IGCSE exam a few years ago:

FInd the percentage of each shape that is shaded. The radii in diagram 6 are 2 and 5.

If I remember, the percentage of students who got full marks on this question was extremely low.

I couldn't imagine them ever putting a question like that in a GCSE exam. Twitter would blow up.

I sitll find that reaction crazy. It's a standard A* question and similar to ones I've seen in old GCSE and IGCSE papers.

If any GCSE students want a challenging paper, take a look at the Edexcel June 2004 non-calc. The A* boundary was only 61%.

its probably something to do with the difficulty some pupils had with picking out the relevant maths from the wordy scenario or maybe removal without replacement stumped people?

but i agree, it was definitely over-hyped in terms of difficulty
