Documents revealing grade boundaries set by exam board Edexcel show that just 165 out of 300 marks were needed to achieve an A grade in England, Wales and Northern Ireland.

Exam board Edexcel has launched an investigation into how part of an A-level maths paper was leaked online. Blacked-out images of two questions were shared on social media on Thursday afternoon.

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.

Students sitting A-Level exams have complained after they were set an Edexcel Maths C1 non-calculator paper which contained questions they say required a calculator.

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.

Students have launched a petition calling maths A level exams 'completely unreasonable' after struggling to answer questions on this year's test.
