99% of all OCR’s GCSE and A Level exams are now marked online. This page will to help you understand what this means. We often get questions about how grade boundaries work and here we answer students’ questions on this popular topic.

Here’s a short video (made in partnership with RM Results) explaining how students’ exam papers are scanned and then marked by examiners on their computer screens.

‘What is a grade boundary?’, ‘Why do grade boundaries have to change every year?’ and ‘How much can a hard exam change the boundaries?’ These are some of the students’ questions we answer in our podcast, hosted by OCR’s grade boundary expert, Mike Forster. Thanks to The Student Room for providing the questions.
