So I got an A* in my Biology GCSE edexcel, and an A* indivudally for b1, b2, b3 inside of it. But im confused by this UMS thing. The papers were out of 60. On the b2 i got 76/80 UMS. But i dont remember doing so well on the b2. Is there anyway to convert this mark to an out of 60 grade? Because im confused on how I got so high in the B2.
