Tables detailing which marks students need to achieve the top grades have been published ahead of A-level results day.

Those who have taken their exams can now find out the grade boundaries on exam board's website before they collect their results tomorrow, Thursday August 17.

A-level exams were changed earlier this year, by former Education Secretary Michael Gove, in an attempt to improve standards.

However, according to The Sunday Times, exams regulator Ofqual has reportedly lowered grade thresholds for the harder exams to ensure that as many pupils pass this year across the country as they did last year.

Many A-level students' university places are offered on the condition that they achieve certain grades. Some qualifications use uniform marks - where the exam board converts your test score into a relative grade.

Uniform mark boundaries do not change every year, but the marks they are calculated from can. Students can check each exam board's website to find out what score is needed for each uniform mark this year.

Students can also check what score is needed for each specific A-level and As grade. For example, if a student took AQA Physics B Unit 6X, they will need a score of 38 for an A, 35 for a B and 32 for a C. The boundaries can be pushed up if examiners felt a paper was not as challenging as a previous year.

Students can check out the exam board's websites to know what scores is needed. Click here for Council for the Curriculum, Examinations and Assessment, here for Pearson/Edexcel and here for Oxford, Cambridge and RSA boundaries.
