Fees and funding
Fees
Tuition fees for home students commencing their studies in September 2025 will be £9,250 per annum. Tuition fees for international students will be £36,500 per annum. For general information please see the undergraduate finance pages.
Policy on additional costs
All students should normally be able to complete their programme of study without incurring additional study costs over and above the tuition fee for that programme. Any unavoidable additional compulsory costs totalling more than 1% of the annual home undergraduate fee per annum, regardless of whether the programme in question is undergraduate or postgraduate taught, will be made clear to you at the point of application. Further information can be found in the University's Policy on additional costs incurred by students on undergraduate and postgraduate taught programmes (PDF document, 91KB).
Scholarships/sponsorships
The University of Manchester is committed to attracting and supporting the very best students. We have a focus on nurturing talent and ability and we want to make sure that you have the opportunity to study here, regardless of your financial circumstances.

Aims
This unit aims to provide an introduction to the algebraic structures of rings and fields, describing the quotient structure and its connection with homomorphisms of rings and presenting important examples with particular emphasis on polynomial rings.
Learning outcomes
On the successful completion of the course, students will be able to:
- Describe and apply properties of primes and division in the integers.
- Define rings, domains and fields and describe standard examples.
- Recognise and construct special types of elements in rings and fields.
- State and recall proofs of properties of rings and ring homomorphisms and apply these to standard examples.
- Recognise ideals and use ideals to construct factor rings.
- Describe properties of polynomial rings and calculate factors and greatest common divisors of polynomials over a field.
- Describe Kronecker’s Theorem and use it to construct roots of polynomials and field extensions.
