As a current OU student, I study alongside a lot of people who don’t fully understand the OU classification system. It isn’t so dictated by straight % like at brick universities as their grade boundaries change. It isn’t always 85% to achieve a grade 1. In one history module they lowered this to 79% and people’s EMA grades were adjusted accordingly, appearing lower than their TMA scores.
*Edit, also, originally offered the opportunity to defer and take any EMA or exam next academic year so hopefully that’s still an option for people not satisfied with the grade they received?
