A Level Further Maths is excellent preparation for the mathematical demands of STEM (science, technology, engineering and mathematics) subjects at undergraduate level at university.
A Level Further Maths is required for a lot of degree courses in mathematics at top universities. For example, Further Maths A Level is required for the undergraduate degree in mathematics at Imperial, Cambridge, UCL and Warwick. For mathematics combined degrees at LSE, A Level Further Maths is expected. At some universities, for example, Leeds, applicants with A Level Further Maths receive a lower offer for acceptance to their Mathematics undergraduate degree.
A Level Further Maths is highly encouraged for a lot of other degree courses in subjects such as Physics, Computer Science, Economics and Engineering at top universities. For example, A Level Further Maths is recommended for the Computer Science, Physics and Aeronautical Engineering degrees at Imperial, and the Mathematics and Engineering degrees at Oxford, and is strongly encouraged for the degrees in Computing, Engineering and Economics at Cambridge. A Level Further Maths is preferred for the undergraduate degree in Engineering at UCL, is helpful for the undergraduate degrees in Physics and Engineering at Oxford and is desirable for the undergraduate degree in Economics as LSE.
You should check the specific requirements of any undergraduate degree course that you are considering apply to on the university’s website.
