Grade boundaries for Edexcel ‘s maths A-level show students who gained 165 out of a possible maximum of 300 marks (55 per cent) will be awarded an A.

Leaked documents show that A level maths candidates had to get just 55 per cent of answers correct to score an A grade this year.

Two questions, apparently from Edexcel’s A-Level Maths Paper 3, were shared on social media on Thursday evening ahead of Friday’s exam, sparking fury among students and parents.
