No there's two types of combined science. Combined science: trilogy (sorry used wrong word) or combined science: synergy. I assume you do trilogy, where you do all science but get two grades?
It's fine most people dont know theres types of combined science. I'm assuming you've done test in biology only right? Like any mocks or assessment or homework?
Edit: you actually need a grade 6 in combined science for psychology!! Not just biology
Yes I’ve got a 6 in my biology mocks but I think I got grade 5 in chemistry and physics so it will bring my grade down? Is there any way of showing the sixth form that I got a grade 6 even though my combined grade might not show it?
Do you or have the school have any evidence of that 6 like do you have that mocks? If so, you can show those to the school as evidence you can get a 6 in biology even if your combined grade might not show.
It says at least a grade 6 in biology/combined science
