Natural Sciences (NST) is the framework within which most science subjects are taught at Cambridge. If you want to study any of the biological and physical sciences, this is the course for you. Natural Sciences (NST) offers a wide range of physical and biological science subjects from 16 departments in a unique and demanding course. A broad first year is combined with increasing specialisation in the second year and the possibility of total specialisation in the third year. The breadth of the course reflects the blurring of boundaries between the different sciences and before committing yourself to one department you study a variety of subjects, some of which may be new to you. This means you can change your mind about which subject to specialise in.
