Under the letter grade scheme, foundation tier papers assess content at grades C to G, while higher tier papers assess content at grades A* to C. In foundation-tier papers, pupils can obtain a maximum grade of a C, while in a higher-tier paper they can achieve a minimum grade of a D. Higher-tier candidates who miss the D grade by a small margin ...
