The differences between the way schools are doing mocks is really concerning. You have some schools writing their own papers based on only a small part of the subject, some schools allowing open book papers, others not, schools making up more generous marking schemes, some exams done in the classroom without proper supervision and I've just read on another thread of a school doing theirs online. How can any of this be fair if these are going to count towards a final grade? I'm really hoping GCSES go ahead in 2021 as it just seems like a complete farce.
