Perhaps you all want to know what goes on in England. Here is a sample GCSE maths exam, taken at the end of year 10, or later, or still later. 3 exam papers in all. This is at the “higher”level and it shows what is expected by any student wanting to go on to higher education (University).

There is a foundation level as well, in which the top grade is deemed OK for college.
