Maths savvy students from Harrow College have taken part in two challenges flexing their numerical skills.
The first competition was the UK Senior Mathematical Challenge, which took place on Thursday 6 November.
The second competition was the UK Senior Team Maths Challenge, which took place on Monday 17 November.
Eight students attended the UK Senior Mathematical Challenge, which took the form of an exam without the aid of a calculator.
Taking part were students Abdifitah Alasow and Samad Rashid, who were awarded silver certificates, and Viktoria Noel and Xiao Chen, who were awarded bronze certificates.
During the UK Senior Team Maths Challenge four Harrow College students took part, including Chen and Noel, as well as Olugbemi Moronfulu and Farhana Pinki.
The challenge included a crossnumber task and a mathematical relay race, which saw the Harrow College team eventually come in twelfth place out of all the schools and colleges that attended.
