@ Kieranw5 my teacher got a rough idea from aqa that 40 is an A and 50 was A* for specimen and so you may have not done as bad as you think. Also if anyone else interested I would say an A is 65-75% is an A and anything above is A*, but some theories are that an A can drop to 55% if really hard but go for 65-75% as that is a safe bet compared to 55%
