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.

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.

Questions from today's A-Level exam leaked online before the test. Two exam questions from Edexcel's maths paper 3 appeared on Twitter last night.

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.

It is the third year in a row that Edexcel A-level maths paper questions have been leaked, after it also previously happened in 2017 and 2018.

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.
