Bachelor of Science
The GY301 Bachelor of Science degree programme allows you to take a variety of subjects in Science before you decide which scientific area to specialise in for your four-year honours degree. It is the ideal choice for students who are interested in several areas of science and who want the flexibility to explore their scientific interests further before committing to a particular specialism.
The programme provides a solid foundation in Science subjects in the first year, with module offerings in Biology, Chemistry, Physics, Mathematics, Mathematical Studies, Computing and Applied Mathematics.
Progressing into second and third year you can choose from a wide range of 20 different specialties, referred to as pathways, including Chemistry, Medicinal Chemistry, Biochemistry, Microbiology, Plant and AgriBiosciences, Botany and Plant Science, Zoology, Earth and Ocean Sciences, Physics and Applied Physics, Physics and Climate Physics, Mathematics, Applied Mathematics, Computing, Data Science, Anatomy, Physiology, Pharmacology.
You can study up to three of those pathways in Year 2, continuing with up to two pathways in Year 3, before choosing a single specialism for Year 4 of the programme, giving flexibility to discover your unique interests and build a tailored skillset that will lead you onto your scientific specialism. To ensure quality in student experience, places in some pathways are limited, a quota system applies to pathways in Year 2.
The pathways are designed and delivered by research-active lecturers and thus incorporate course content inspired by current research trends, including public policy and industry partnership, whilst emphasising the importance of science communication. Our curricula embed sustainability and the principles of the UN’s Sustainable Development Goals, feature innovative teaching methods, and draw on our wide range of strengths from across the sciences at University of Galway.

Mode of study
In each year of the programme a student studies modules to a total of 60 Credits.
A student chooses four 15-credit modules from the following:
- Biology BO101
- Chemistry CH101
- Physics PH101
- Mathematics (Honours) MA180
- Mathematical Studies MA161
- Applied Mathematics MP180
- Computer Science CS102
Each Year 1 module is available to each student of the GY301 Bachelor of Science programme with no limits on places, with only the constraint that students must choose at least one module from:
Year 1 modules are supported by lectures, which provide discussion and demonstration of topics, by tutorials or workshops, and by practical classes offering extensive and hands-on laboratory experience. Students are supported by the CÉIM shared peer learning initiative, by the SUMS Centre (Support for Undergraduate Mathematics and Statistics) and an Advisory Scheme in which each student has a contact point with an academic staff member to help answer general queries throughout their first year.
In Year 2 of the programme students begin a specialised path of study. Modules are grouped by focused themes providing a pathway toward a specialism. Students can study up to three pathways in Year 2, where eligibility for the pathways depends on the combination of modules chosen in Year 1. Note that places on some pathways are limited –
Years 3 and 4
In year 3 of the programme students continue their focused paths of study, retaining up to two pathways, choosing a single specialism in either Year 3 or Year 4. In Year 4 - the final year - students study advanced modules and undertake an intensive research project in their chosen area guided by an academic supervisor, leading to their specialist Bachelor of Science degree.

Glossary of Terms
- You must earn a defined number of credits (aka ECTS) to complete each year of your course. You do this by taking all of its required modules as well as the correct number of optional modules to obtain that year's total number of credits.
- An examinable portion of a subject or course, for which you attend lectures and/or tutorials and carry out assignments. E.g. Algebra and Calculus could be modules within the subject Mathematics. Each module has a unique module code eg. MA140.
- Some courses allow you to choose subjects, where related modules are grouped together. Subjects have their own required number of credits, so you must take all that subject's required modules and may also need to obtain the remainder of the subject's total credits by choosing from its available optional modules.
- A module you may choose to study.
- A module that you must study if you choose this course (or subject).
- Required Core Subject
- A subject you must study because it's integral to that course.
- Most courses have 2 semesters (aka terms) per year, so a three-year course will have six semesters in total. For clarity, this page will refer to the first semester of year 2 as 'Semester 3'.

What Our Students Say
Rachel Cleary | QUALITY TECHNICIAN, CLS
Not knowing which discipline of Science I wanted to pursue, I chose the Bachelor of Science Degree at University of Galway, which offers a basis for fundamental science and a broad foundation for which to specialise upon. I found my feet within the biochemistry department, where lectures and practicals were in-depth, informative and gave me the experience and analytical skills required for my job today. In my Final year project I spent half the year immersed in Laboratory life, where I gained skills in analytical techniques, time management and teamwork, which I felt prepared me for industry. I started working for a laboratory solutions company soon after my degree, and they placed me on contract within a global pharmaceutical company. Here I work within the quality laboratory, using techniques such as High Performance Liquid Chromatography which I first learned at University of Galway.
