The head teacher of a North Somerset school has apologised after a human error which means a hundred pupils won't sit GCSE Science exams they've been revising for this week.

Year Ten students at Backwell School havn't been entered for the correct chemistry and biology modules because of an admin mistake.

Julian Baldwin's written to parents saying the children will now take the tests as mock exams, before doing the real thing in the summer instead - and says the school's confident results won't be 'adversely affected'.
