Grade Boundaries for Physics and Chemistry are shocking and unfair.Grade Boundaries for French are good and the Grade Boundary for Geography is wonderful.I think that grade boundaries should always be kept low as a rule because grade boundaries like 51 for an A* in Physics only discriminate against good pupils through the silly and daft mistakes, which I feel isn't a fair system.Papers should be made harder to be more challenging and to prevent really clever people, from losing out for silly mistake and this system would give A*s to pupils who hasd risen to the challenge and conquered the really tough, extension of spec questions and not missed out by silly mistakes.
