does a d grade count as a gcse
GCSEs are awarded on a graded scale, and cross two levels of the Regulated Qualifications Framework (RQF): Level 1 and Level 2. These two levels roughly correspond, respectively, to foundation and higher tier in tiered GCSE qualifications. Level 1 qualifications constitute GCSEs at grades G, F, E, and D or 1, 2, and 3. Level 2 qualifications are those at grades C, B, A, and A* or 4, 5, 6, 7, 8, and 9.
