The BSc in Marine Biology is a four-year course run by the School of Biology. Students are provided with high-tech equipment, laboratories and expertise to facilitate learning and to develop the skillset of a modern marine biologist.

In the first two years of the degree, students will take the core modules in biology along with modules intended to prepare them for advanced modules in Marine Biology specifically.  

Alongside biology, 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, enquiry-based learning.

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