Richard Earl is a departmental lecturer in the Mathematical Institute, University of Oxford, and a Tutor in Mathematics at Worcester College. From 2013-2022 he was Director of Undergraduate Studies in the Institute. From 2003–13, he was Admissions Coordinator and Schools Liaison Officer in the department and has over a decade's experience setting the MAT (Oxford's Mathematics Admissions Test). He has won several teaching awards within the University for his teaching and lecturing. This book grew out of a residential week he ran for several years in Oxford for new students who had not had the chance to study Further Mathematics at A-Level. He is currently the academic lead on the Mathematics and Computer Science Opportunity Oxford programme which includes a fortnight-long residential prior to the academic year and which supports students in their transition to university.
