The 3 math papers of gcse are a math paper without calculator and 2 math papers with calculator for the basic level, and a math paper without calculator and 2 math papers with calculator for the upper level. One example is that, CIE has a reputation for being easier than Edexcel for English and more difficult for mathematics. Again, students can be evaluated on any of the topics described above, although in Document 2, a calculator is allowed. Document 2 has a duration of 2.5 hours with expanded answers to more detailed questions, which is a very useful preparation for the prolonged problems found in the Level A standard.
AQA papers carry the same weight, putting less pressure on students to perform better in one than in another.
