In all subjects, Edexcel is the most popular examining board among UK students taking IGCSE, and it is also the easiest. The most difficult is Pearson Edexcel, and the IGCSE branch of the rating in particular. Within this, there are fewer papers to be seated than AQA, but the allotted time is shorter. Mastering Mathematics and Problem Solving books are good sources for applied and interspersed questions, especially useful for increasing student exposure to questions in a variety of contexts.
While there are very few differences between what exam boards look for in a specific question, it is worth noting that if the question is worth, for example, 5 points, you must make 5 distinct points, the last of which will be your final answer. It would be wise to look carefully at previous papers to compare the styles of gcse math questions and paper presentation to make an informed decision about what would be best suited for your students. You may want to reflect on whether a greater chance of earning method grades is more appropriate for your students and whether placing non-calculator paper first or second informs your readiness for teaching and testing. The content of the subjects in the three boards is also the same as that set out in the content document of the GCSE Mathematics subject of the Department of Education.
Edexcel provides exam practice support by presenting your questions in a variety of ways, such as by subject and scaffolding levels, as seen in its gold, silver, and bronze documents. There are five GCSE councils covering England, Wales and Northern Ireland, and finding programmes that could improve students' chances of achieving good results seems to be an important factor in decision-making.

Another teacher, however, was not so convinced that OCR exams were easier than AQA ones, and wrote that he would stay with AQA because he had simplified his documents for a new version of the exam that would be released in September.
However, most of the time, the school builds it on what they have taught in previous years (since that makes it easier to prepare resources) and on the exam board that they think will be easier to teach and on which students are most likely to get the best grades. The fact that Edexcel had bet himself in the middle was not a big surprise, while some students preferred simple OCR questions or more complicated AQA examples, most students preferred a combination of both. All examining boards state that papers increase in difficulty in terms of content and language as work progresses, but one notable difference with AQA is the presence of multiple-choice questions at the beginning.
