GCSE students from schools across Huddersfield put their heads together to boost their exam revision.
And they gave up part of their school holiday to do so.
About 150 youngsters volunteered to take part in revision classes at Huddersfield New College to prepare themselves for GCSE exams in maths and English this summer.
Teachers from Greenhead College and Huddersfield high schools helped run sessions. Pupils worked in groups of six to brush up on their studies.
New College vice-principal Steve Wetton said: "The enthusiasm and work ethic of the students is a credit to their schools and teachers.
"They have all given up a day of their holidays to do extra work.
"They all deserve to pass their exams."
