Biology is probably the most accessible of the three science, as it can be related naturally to all aspects of life. To study A-level Biology you don't need advanced mathematics and you don't have to remember long Latin names.
On the A-level Biology course you study carefully and in detail how life in the world works: how our bodies work; how diseases stop them working; how plants grow; how life may be threatened by poisonous substances; how ecosystems work; where energy comes from and how organisms use it; how genes and evolution affect us all.
