What is a BSc degree?

A BSc degree, short for Bachelor of Science, is one of the most common undergraduate qualifications in the UK. It is typically awarded for subjects that focus on science, technology, mathematics, data and analytical disciplines. 

If you are considering university or exploring your higher education options, understanding what a BSc degree involves can help you decide whether it is the right path for you. 

What does BSc stand for? 

BSc stands for Bachelor of Science. In the UK, it is an undergraduate honours degree that usually takes: 

• Three years to complete if studied full-time 

• Four years in Scotland, or if the course includes a foundation year or placement 

• Longer if studied part-time 

A BSc degree is equivalent in academic level to a BA degree, but the subject focus and teaching style often differ. 

What subjects are BSc degrees awarded in? 

BSc degrees are most associated with science and technical subjects, but the range is broader than many people expect. 

Common BSc subjects include: 

• Computer Science 

• Psychology 

• Biology 

• Biomedical Science 

• Mathematics 

• Economics 

• Engineering 

• Environmental Science 

• Data Science 

• Nursing and Health Sciences 

Some universities also award BSc degrees in subjects such as Business Management, economics or sports science, particularly where the course has a strong analytical or quantitative focus.

How is a BSc degree taught? 

Teaching methods on a BSc degree tend to be practical and evidence-based, though this varies by subject and university. 

You may experience: 

• Lectures and seminars 

• Laboratory work or practical sessions 

• Group projects 

• Coursework and exams 

• A final-year dissertation or research project 

Many BSc degrees place a strong emphasis on problem-solving, data analysis and applying theory to real-world situations, including in applied subjects such as Business Management. 

What is the difference between a BSc and a BA degree?  

The main difference between a BSc and a BA (Bachelor of Arts) degree is the subject focus, not the academic level. 

In simple terms: 

• BSc degrees focus on scientific, technical and quantitative subjects 

• BA degrees focus on humanities, arts and social sciences 

That said, there is overlap. For example, Business Management, psychology or economics may be offered as either a BA or a BSc, depending on the university and course structure.

What classification can you get in a BSc degree? 

Like most UK undergraduate degrees, including BSc (Hons) programmes, BSc degrees are awarded with a classification: 

• First Class Honours (First) 

• Upper Second Class Honours (2:1) 

• Lower Second Class Honours (2:2) 

• Third Class Honours 

Your classification is based on your overall performance across the course, usually with more weight given to later years of study.

Is a BSc degree good for careers?  

Yes. A BSc degree is highly valued by UK employers, particularly in sectors such as: 

• Technology and IT 

• Healthcare and life sciences 

• Engineering and construction 

• Finance and data analysis 

• Business, management and consultancy 

• Environmental and sustainability roles 

A BSc degree can also be a stepping stone to postgraduate study, such as an MSc degree, PGCert or PhD. 

Entry requirements for a BSc degree in the UK 

Entry requirements vary by university and subject, but typically include: 

• A-levels or equivalent qualifications 

• GCSEs in English and maths 

• Subject-specific requirements for science or technical courses 

Many universities also accept BTECs, Access to Higher Education Diplomas and international qualifications. Foundation years are available for students who do not meet standard entry requirements. 

Is a BSc degree right for you?  

A BSc degree may be a good choice if you: 

• Enjoy analytical, numerical or evidence-based subjects 

• Like problem-solving and structured thinking 

• Want strong career prospects across technical and professional fields 

• Are considering postgraduate study 

If you prefer more theory-led or essay-based subjects, a BA degree may be a better fit. 

Final thoughts 

A BSc degree is a respected and versatile undergraduate qualification in the UK. Whether you are interested in science, technology or applied subjects such as Business Management, a Bachelor of Science degree can open the door to a wide range of academic and career opportunities.
