<P> 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 . 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 . </P>
