About 70 GCSE pupils from Grange Upper School in Bradford are giving up part of their weekend for lessons in English, maths and science.
Six teachers have agreed to take the classes held between 10am and 1pm. Parents pay a token Pounds 2 to take part in the experiment, which costs the school Pounds 300 each Sunday.
It is part of an attempt to turn around the school, which has 1,100 pupils, 85 per cent of Asian origin, with many of them speaking English as a second language at home. Only ten per cent of pupils gained five GCSEs at grades A to C this year.
Headteacher Richard Thompson said the pupils had a tremendous thirst for work and education.
The school is one of a growing number in inner-city areas offering after-hours homework clubs to enable pupils to improve their exam prospects.
