Suppose your employer asks you to design a net for a can of pumpkin pie filling. The diameter must be 0.10 m, and the height must be 0.14 m. However, the cans will be exported to the USA, and all dimensions on the net must be labelled in inches. Draw the net using a scale of 1:2. Show your calculations and round your answers to two decimal places.
What mathematics is included on the test? It is hard to give you advice without knowing what kind of practice on what types of problems you are looking for.
When I searched for Edexcel past papers I could see Mathematics A - Paper 1 Mathematics A - Paper 2 Mathematics B - Paper 1 Mathematics B - Paper 2
Which means, does a student have to write 4 Maths exams for GCSE? When I looked at the Edexcel time table for June 2015, I could only see 2 papers (Maths A, Maths B) on June 4th and June 8th. I'm a bit confused, Could you give me an idea about this please?
(I know about Foundation and Higher tiers. I am talking about Higher tier here)

You must also Add OR subtract from left to right as they appear in the problem
Hope this helps!

but I think you may be right. I like it.
a*b/c done left to right works out to ab/c
a*b/c done division first works out to ab/c
a/b*c done left to right works out to ac/b
a/b*c done division first works out to ac/b
I leave the subtraction case for dear Michelle, who should understand that someone who signs themselves as Math Teacher probably wasn't asking how the order of operations rules work, but was raising a deeper point.
It is a long time since I was surprised by something in what we would consider elementary math, but you have done it. Kudos.
