These study materials are based on the Edexcel and MEI specifications for Further Pure Mathematics 1. There is, however, a lot of crossover with other boards. I have added the roots of polynomials topic specifically to help students doing MEI FP1, and the graphing rational functions topic is on the way.
FP1 forms a foundation for the mathematics you may later study at university, introducing complex numbers, matrices, and numerical methods, all of which are fundamental for science and engineering degrees.
Obviously this is a fantastic course for budding mathematicians too. You will be introduced to proving mathematical statements and explore deeper into topics that are glazed over in standard A-level mathematics.
