when was the a* introduced at a level
GCE Advanced Level (United Kingdom) The pass grades for A Levels are, from highest to lowest, A*, A, B, C, D and E. The process to decide these grades involves the uniform mark scheme (UMS). Under this scheme, four-module A levels have a maximum mark of 400 UMS (or 200 UMS each for AS and A2), and six-module A levels have a maximum mark of 600 (or 300 UMS each for AS and A2). The maximum UMS within AS and A2 may be split unequally between each modules. For example, a Physics AS may have two exam modules worth 90 UMS and 150 UMS, and a coursework module worth 60 UMS. The 'raw marks' i.e. actual score received on a test may differ from UMS awarded. On each assignment, the correspondence of raw marks to UMS is decided by setting grade boundaries, a process which involves consultation by subject experts and consideration of statistics, aiming to keep standards for each grade the same year on year. Achieving less than 40% results in a U (unclassified). For passing grades, 40% corresponds to an E grade, 50% a D, 60% a C, 70% a B, and 80% an A. The A* grade was introduced in 2010 and is awarded to candidates who average 80% UMS across all modules, with a score over 90% UMS in all A2 modules.[14] In Mathematics, which comprises six 100 UMS modules, only the C3 and C4 modules count towards this requirement. In Further Mathematics and Additional Further Mathematics, where more than three A2 modules can be taken, the three best-scoring A2 modules count. There is no A* grade at AS level.
