Hi I have just done my mocks in combined science and gta 8-8 , I think I done extremely well in Biology and Chemistry but awful in Physics , could you please tell me how it is grades since there is only 2 GCSE’s e.g. if I got a 9 in Chemistry and Biology but a 5 in Physics how is it worked out I got to 9’s?
Your marks are added together and it is out of 420. Check grade boundaries but it goes 9-9, 9-8, 8-8 and so on.
Your mark will correspond with a certain grade on the grading scale for combined science (which is a bit different from the other subjects as you have seventeen grades on the scale from 1-1 to 9-9). It's just like any other subject, except with more grades. I too achieved an 8-8 (but in my real exams), and this is how it was calculated.
