Two teenagers try to improve their poor grades by moving in with a star student in the new documentary Living with the Brainy Bunch.

How much of what happens at school is linked to the home environment? Could a radical change in family life turn a tricky teen into a dream pupil?

That’s the premise behind this one-off documentary, which takes two under-achieving 15-year-olds, who will be taking their GCSE exams in nine months, and places them in the homes of straight-A students.

For six weeks, disillusioned Hollie will move in with head girl Holly, and Jack, who has had over 100 detentions, will live with multi-lingual Tharush, who recently moved to the UK from Italy.

Will the strict family routines help focus the pair or frustrate all concerned?
