The Mathematics Department is the largest in the school teaching all students in Years 7 to 11. Mathematics is the most popular Sixth Form subject with around 150 students taking A level Maths each year and 50 taking Further Maths. There are 5 or 6 Maths classes as well as 3 Further Maths classes in each of Year 12 and Year 13.

All Maths staff are highly qualified subject specialists who consistently help our students achieve the very best they are capable of, promote Maths throughout the school, and inspire a love of Maths so that learners are confident, resilient problem solvers.

A-level Mathematics (Edexcel exam board) students opt for the subject for a number of reasons: to pursue Maths beyond GCSE; for a valued qualification that facilitates their applications to a broad range of highly-regarded university courses; or to underpin their mathematics knowledge for other subjects such as Economics and the sciences. The school has a long tradition in  A-level Further Mathematics (Edexcel exam board) where our experience and expertise has continually ensured outstanding results. Universities have welcomed the school’s emphasis on Further Mathematics for maths and related subjects.


The Department is proud of the part it plays in the wider aspects of school life at CRGS and there are ample opportunities for extra-curricular mathematics throughout the school including participation in the UKMT Maths Challenges. We also regularly have a large number of students progressing to the follow-on Kangaroo and Olympiad rounds. Year 12 and 13 students organise the very successful Physics and Maths Society where students themselves prepare and present talks on a wide variety of topics of interest beyond the syllabus.

Older students are encouraged to attend lectures in London or Cambridge to broaden their exposure to Maths in the real world.

The department is forward thinking and always looking for new ideas to enhance and enrich the mathematical experience of students.

Support sessions, Gifted & Talented and Mentoring

To ensure that each student is fully supported during their time at CRGS, the Maths Department office is “always open”. Students are encouraged to seek individual help at break or lunchtime and older students are involved in mentoring students in the lower school at lunchtimes for both support and extension work.

We offer a lunchtime ‘Maths Clinic' for Year 12 and 13 students which is always buzzing.

A large number of students apply to Oxbridge and other leading universities in the UK, Hong Kong and America either for Maths or a course where Maths is an essential access subject, and the department has a high success rate in preparing and supporting students through the application process including for entrance exams such as MAT, TMUA and STEP.
