A secondary school has driven its way to third place in a national efficiency competition.

Leon School and Sports College beat 24 other schools in the Shell Eco-Marathon Youth Challenge, by building a car 61 times more efficient than a Ford Mondeo.
The Bletchley school's team had to design and build a vehicle with optimum efficiency, and was given the chance to test it at Rockingham Motor Speedway on Monday, July 6.
The best teams had to consider the aerodynamics, rolling resistance, engine efficiency - and complete the course with a minimum speed of 15mph.
Leon achieved this with the winning mileage of 1533.8 miles per gallon, coming third in the "Schools Initative class", a specialised group for schools competiting in their first three years of this car competition.
Jhita Rupinder, from Leon, said: "It is really impressive how they suddenly grow up and mature over the duration of the competition. Their parents are really happy that the children get the opportunity to compete and be in a team. It raises their aspirations at the same time as developing a wide range of skills; maths, science, teamwork, communication and design technology to name a few."
The competition has been running alongside other Eco-marathon events for more than 30 years. This year, the British competitors were even joined by foreign guest teams from universities in France, Portugal, India, Finland, Italy and Switzerland.
To Paul Snaith, the managing director of Shell Research Ltd in the UK, it is not just the winning that counts.
He said: "Engaging the next generation of scientists and engineers while they're still in the classroom is incredibly important. The Shell Eco-marathon Youth Challenge aims to ignite their interest and help them learn the skills they need for the future."
The company also runs The Shell Education Service which offers workshops for children to help develop their knowledge of science.
