Computer Science BSc

Computer Science is the study of computation, software and systems. It underpins modern technology and drives innovation across industries from healthcare and finance to gaming and artificial intelligence. A Computer Science degree equips students with programming, problem-solving and analytical skills, preparing them for diverse roles in technology and beyond. It is an excellent choice for students who are logical thinkers, creative problem-solvers and passionate about technology.

Course Structure

Most Computer Science degrees last three years full time, or four years with a placement year or study abroad. Some universities also offer integrated master’s programmes (MSci/MEng) that extend study to four or five years. Many courses are accredited by the BCS, The Chartered Institute for IT.

Teaching combines lectures, seminars, practical programming labs, hackathons, team projects and research. Assessments usually include exams, coursework, coding projects, group assignments and a final-year dissertation or major project.

Useful A-Level or BTEC Subjects

Entry requirements vary, but useful subjects include:

• A levels: Mathematics is typically required. Computer Science, Physics or Further Mathematics are also excellent choices.

  
  

• BTECs: Computing, IT or Engineering may be accepted, sometimes alongside A level Maths.

  
  

• International Baccalaureate: Higher Level Maths and Computer Science are usually preferred.

  
  

• Strong mathematical ability and logical thinking are key to success.

What Makes a Strong Application

Universities look for students who show both technical aptitude and curiosity about technology. A strong application should include:

• Good grades in maths and related subjects.

  
  

• Relevant experience or projects, such as coding personal apps, websites, or open-source contributions.

  
  

• A personal statement demonstrating passion for computing, problem-solving and innovation.

  
  

• Evidence of initiative, such as participation in coding clubs, hackathons, or online courses (e.g. Python, JavaScript, or AI).

Transferable Skills You Will Develop

A Computer Science degree provides a wide range of professional and transferable skills, including:

• Programming expertise – coding in multiple languages.

  
  

• Problem-solving – breaking down complex technical challenges.

  
  

• Data analysis – working with big data, algorithms and machine learning.

  
  

• Communication skills – explaining technical concepts clearly.

  
  

• Project management and teamwork – collaborating on software projects.

  
  

• Adaptability – keeping pace with emerging technologies.

  
  

Wider Reading: Recommended Books for Aspiring Computer Science Students

Here are four accessible and inspiring books:

“Code: The Hidden Language of Computer Hardware and Software” by Charles Petzold – A clear introduction to how computers work.

“The Pragmatic Programmer” by Andrew Hunt and David Thomas – A classic on software craftsmanship and good coding practice.

“Artificial Intelligence: A Guide for Thinking Humans” by Melanie Mitchell – An accessible look at AI today and its future.

“Algorithms to Live By” by Brian Christian and Tom Griffiths – Shows how computer science principles can solve everyday problems.

Typical Pay After Graduation

Computer Science graduates are in high demand. Starting salaries for roles such as software developer, IT consultant or systems analyst are typically £28,000–£35,000. With experience, mid-level roles such as software engineer or data analyst earn £40,000–£55,000. Senior roles in AI, cyber security, data science or IT architecture can command £70,000–£100,000+, particularly in finance and tech industries.
