    For the eye you only need to learn how to label and the role of the cornea for example but nothing else

    Basic knowledge really - fsh develops egg and stimulates oestrogen, lh releases egg. Sure theres nothing on the corpus luteum or anything.

    How the structure of a villus cell helps absorption of the products of digestion in the small intestine.

    I think it went quite well. The only 5 marker I had a problem with was the question about the bacteria and the growth hormone on the 2nd to last page. Completely forgot about that!! Other than that it was good
