“Studying at St Andrews has given me much more than just education. It has instantly given me the feeling of home and it never ceases to amaze me how much the University cares about the wellbeing of the students. Thanks to the flexibility of the schedules, I was able to engage in other sciences besides Biology in the first year, and explore different aspects of the subject in the second year.”

Course details

The BSc (Hons) 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 biology, in the first year of your studies you will be required to study an additional two subjects. In the second year, you will usually carry on at least one of these subjects, sometimes two. Find out more about how academic years are organised.  

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.

Centres of research within the School of Biology offer students the experience of working alongside experts and the opportunity to develop their own research in Honours years. 

These facilities include: 

  • The Scottish Oceans Institute houses a modern aquarium and laboratories for molecular, developmental and physiological studies of marine systems. The institute is ideally placed on the seashore near grey and common seal colonies and bottlenose dolphin feeding areas. 
  • The Centre for Biological Diversity has excellent facilities for behavioural, ecological and evolutionary research on animals (including birds and insects) and plants. Many members of the CBD also run active field studies as part of their research, allowing access to field-based projects as well as laboratory studies.  
  • The Biomedical Sciences Research Complex offers large multi-group laboratories which are focused on structural biology, molecular microbiology, virology, chemical biology, cell biology and molecular medicine. 

Field trips

From first year to Honours, students studying zoology will also have the opportunity to go on field trips to gather data. During third year, zoology students participate in a week-long field course involving field-based exercises in a range of aquatic or terrestrial habitats. Students will be able to examine and measure biodiversity, ecophysiological adaptation and community structure with both plant and animal materials. 

The University of St Andrews operates on a flexible modular degree system by which degrees are obtained through the accumulation of credits. More information on the structure of the modules system can be found on the flexible degree structure web page.

Modules

In the first two years of your degree (known as Sub-Honours), you will take the required modules in zoology alongside modules in at least one other subject. 

Typically, you will take core zoology modules during your first two years, and advanced modules during your third and fourth year (known as Honours).

In first year, modules introduce you to core subject material relevant to all biology degree programmes. Both of the following modules are compulsory:

  • Biology 1: provides an introduction to molecular and cellular biology. It covers cell diversity and the origins of life, evolution, cellular structures and fundamental processes. 
  • Biology 2: provides an introduction to the diversity of life on Earth and addresses key elements of organismal, behavioural and ecological aspects of life.

In second year, modules are chosen which will best prepare you for your intended degree (or group of possible degrees) and new topics are introduced in some second-year modules. Students intending to study zoology at Honours level must take the following compulsory modules:  

  • Animal Behaviour:  covers the four ways in which we explain behaviour in a range of animals, including examples from all major taxa and from all habitats.
  • Invertebrate Zoology: surveys the major invertebrate groups, emphasising the diversity of body plans while demonstrating how the common functional requirements such as feeding, reproduction, respiration and excretion are achieved. 
  • Research Methods in Biology: develops essential academic and transferable skills, with major emphasis on problem solving. This is achieved through a combination of interactive lectures, independent data-handling workshops and group work on a mini research project. 
  • Vertebrate Zoology: explores the diversity of vertebrate animals, providing a detailed look at the defining characteristics of the body plans and lifestyles of the key vertebrate group.

In third year, you will continue to specialise in zoology via a wide range of modules covering core topics. Modules that have been offered in previous years include: 

  • Animal Behaviour: A Quantitative Approach 
  • Biology of Marine Organisms 
  • Ecosystems and Conservation 
  • Evolution 
  • Genes, Cells and Development 

In fourth year, you will study your chosen subject area at a deeper scientific level and will also have the opportunity to select from a wide range of small-group, specialised modules. These modules are taught by academics at the forefront of their discipline. 

In this year, students can also undertake a substantial final-year research project. This research project is designed to develop skills in experimental design and problem-solving, the evaluation and interpretation of data, and communication skills.  The project is offered and supervised by a member of academic staff.

The modules above are examples of what has been taught in previous academic years and may be subject to change before you start your course. Please see the module catalogue for more details of each module, including weekly contact hours, teaching methods and assessment.

Teaching

The BSc in Zoology is taught through a combination of: 

  • lectures 
  • seminars 
  • tutorials 
  • practical classes 
  • field work

The practical elements of the course, which are taught in state-of-the-art teaching laboratories and in the field, enable you to learn the wide range of skills required of a modern biologist. Alongside the development of practical biological skills, students are also given the opportunity to expand on their presentation and IT skills.  

Typical class sizes include: 

  • First year: lectures 250 to 300 students, practicals 80 to 100 students 
  • Second year: lectures 80 to 175 students, practicals 40 to 60 students 
  • Third year: lectures 20 to 140 students, practicals 20 to 60 students 
  • Fourth year: 5 to 25 students per module

Fourth year allows you to focus on a major project which occupies half of the year. Working on this project will enable you to develop key research skills which are desired by both prospective employers and by graduate schools offering postgraduate degrees. The project can also lead to your first publication in a scientific journal.   

When not attending lectures, tutorials and laboratory classes, you will be expected to continue learning independently through self-study. Typically, this will involve: 

  • working on individual and group projects 
  • undertaking research in the library or in PC classrooms 
  • preparing coursework assignments and presentations 
  • preparing for examinations

First-year Biology modules are entirely assessed by coursework.

During second and third year, most Biology modules are assessed by an equal weighting of coursework and written examinations.

In fourth year, most Biology modules are entirely assessed by coursework, while some include written examinations in addition to coursework.

Most examinations are held at the end of the semester during a dedicated exam diet, and revision time is provided beforehand.

The School of Biology aims to provide feedback on every assessment within three weeks to help you improve on future assessments.

Undergraduates at the University of St Andrews must achieve at least 7.0 on the St Andrews 20-point grade scale to pass a module. To gain access to Honours-level modules, students must achieve the relevant requisites as specified in the policy on entry to Honours and in the relevant programme requirements. To find out the classification equivalent of points, please see the common reporting scale.

You will be taught by a research-led teaching team with expertise and knowledge of zoology. Postgraduate research students who have undertaken appropriate training may also contribute to the teaching of tutorials under the supervision of the module leader.
