Why study Biology?

This course will help you gain some understanding of the exciting nature of Biology today.  It also looks back at some historically important work that underpins modern Biology.

As in all Science subjects, practical activities help to illustrate the theoretical aspects of the course, and they form an important component of coursework. Though traditionally thought of in relation to careers such as medicine, dentistry, and veterinary science, there are many other areas including those in biochemistry, genetics, microbiology, and even law and scientific journalism where the skills gained in the study of Biology can be used.
