We prefer students with a range of maths- and science-based subjects, and your typical offer depends on how many of these subjects you study in your A level subjects.If you study Chemistry and at least two other maths or science subjects: AAB in three A levels including A in Chemistry and two other science or mathematics subjects.If you study Chemistry and only one other maths or science subject: AAA in three A levels including Chemistry and one other science or mathematics subject.If you study four or more subjects and could meet either set of requirements, our typical offer will normally be the lower of the two (AAB). If you are taking a GCE A level in a science subject, you will need to pass any separate science practical endorsement.Alternative offer:ABB or AABMost of our students will join us with three principal subjects, but you may have study beyond this (such as a Global Perspectives course or additional study in maths) which demonstrates your individual talents that will help you with your degree. We recognise these studies through our alternative offers. Like our typical offer, the grades required by an alternative offer depend on the number of science and mathematics subjects you are studying.If you study Chemistry and at least two other maths or science subjects:ABB in three A levels including A in Chemistry and two other science or mathematics subjects plus one of:grade A in an EPQgrade B in the Welsh Baccalaureate Advanced Skills Challenge Certificategrade B in a Core Mathematics qualificationgrade B in AS level Mathematics or Statistics (except if you are studying an A level in that subject)grade B in a fourth principal subject, where your four principal subjects include MathematicsIf you study Chemistry and only one other maths or science subject:AAB in three A levels including A in Chemistry and B in one other science or mathematics subject plus one of:grade A in an EPQgrade B in the Welsh Baccalaureate Skills Challenge Certificategrade B in a Core Mathematics qualificationgrade B in AS level Mathematics or Statistics (except if you are studying an A level in that subject)Or alternatively,AAB in three A levels including A in Chemistry plus one of:grade B in a fourth A level, where your four A levels include MathematicsIf you receive an offer for this course and are studying one of these qualifications you will be given both the typical and alternative offer. If you study four or more subjects and could meet both the AAB and ABB set of requirements, our typical alternative offer will normally be the lower of the two (ABB).
