The BSc in Zoology is a four-year course run by the School of Biology.  The programme begins with a broad foundation across the range of biology, and then progresses from modules in molecular, cellular and organismal biology to a choice of options across a range of topics such as animal behaviour, development, evolution, neurobiology, environmental physiology, sea mammal biology, and various more ecological topics.

Alongside zoology, in the first year of the studies students will be required to study an additional two subjects. In the second year they will usually carry on at least one of these subjects, sometimes two. In third year, there is a shift from core, broad-themed modules to more specialised modules that allow students to prepare for their Honours degree. In fourth year students continue specific research in their chosen area through student-led, inquiry-based learning.

The University of St Andrews operates on a flexible modular degree system by which degrees are obtained through the accumulation of credits.
