    Yep, thats what I wrote and for the bright light its the iris that controls the intensity of the light taken in...
    The way i remembered it was , that your eyes hurt looking at close objects , so your muscles or something have to contract , when it contracts it becomes larger or more curvier

    YOU GET A BIOLOGY GRADE WHICH CONSISTS OF B1, B2, B3 IF YOU DO TRIPLE AND YOUR ISA GRADE.
    You also get a Chemistry and Physics grade in the same way, does that make more sense?

    Makes sense. But once all the marks are added from the b1,2,3 & isa, are there different grade boundaries for grade A, B etc? If so do you know the marks needed out of the total for each grade?

    I would love the additional science physics mark scheme if you have it

    The grade boundaries for each unit and the ISA are different and they equal to different UMS values.
    In the end, you have your total UMS value which determines what overall grade you get, and these boundaries also vary over the years

    No I'm afraid you're incorrect, resistance is measured in ohms
    Charge is measured in coulombs
    Resistance is measured in ohms

    I think I got all the questions right , apart from the one where you had to convert from mm to m , because i got 4.54 D , also maybe a few marks may be dropped away , but i got at least 52.Good paper , agreed.

    The iris has muscles which contract to control the size of the pupil , and therefore can limit light entering eye.

    I don't think spelling matters unless its on the six mark question, as long as it resembles the word "coulomb" then you should get a mark.
