Why study Computer Science?

At Kings we offer Foundation programmes and A-levels which can be studied in the best subject combination to guarantee the ideal preparation for a degree in Computer Science in the UK.

We look at what the subject actually covers, as well as some of the reasons to study it, and some of the careers that it can lead to.

What is Computer Science?

Computer Science is, at its core, the study of computation and information and brings together disciplines that include Mathematics, Engineering, Sciences, Psychology and Linguistics. It includes both the study of theoretical algorithms and the practical problems involved in implementing them through computer hardware and software. The study of Computer Science has many different branches, including artificial intelligence, software engineering, programming, data science, cyber security and computer graphics.

In today’s digital age, most industries are completely reliant on data, software and IT. Computer science impacts all aspects of our lives — from scientific research to transport, banking, communications, medical equipment, and even our household appliances.

With the reach of technology set to increase exponentially throughout the coming decades, the demand for graduates who are skilled within fields such as Computer Science is likely to continue to grow.

The Computer Science Skills Gap

A ‘skills gap’ is where the number of open job positions within a particular sector outweighs the number of qualified professionals suitable to fill these positions. Computer science represents one of the most extreme examples of an industry with a skills gap globally, with the worldwide shortage of IT professionals estimated to be around 1.8m in 2020.

A recent report by Microsoft, titled ‘Unlocking the UK’s potential with digital skills’, revealed that 80% of UK leaders believe investment in digital skills will be important to the country’s post-Covid-19 economic recovery. According to the US Bureau of Labour Statistics, there will be a 13% increase in Computer Science jobs by 2026. In the EU, the number of ICT (Information and Communications Technology) specialists grew by 36.1% over 10 years from 2007–2017.

This skills gap represents a unique opportunity for current high school students to carefully plan their subject choices and undergraduate studies to exploit the current skills gaps and make themselves indispensable to future employers.

Computer Science careers

As the demand for qualified IT specialists is so high, careers within the field of Computer Science are often very well-paid. The average starting salaries in the UK for popular computer science careers are:

  • Game Developer: £24,000, up to £75,000 with experience
  • IT Consultant: £25,000, up to £80,000 with experience
  • Web Developer: £23,000, up to £75,000 with experience
  • Cyber Security Analyst: £30,000, up to £70,000 with experience
  • Data Analyst: £24,000, up to £60,000 with experience
  • Machine Learning Engineer: £35,000, up to £170,000 with experience
  • Network Engineer: £19,500, up to £70,000 with experience

Qualifications in Computer Science may also open to the door to opportunities such as internships or apprenticeships at some of the world’s most famous tech companies such as Amazon, Apple, HP, Microsoft, Google and Vodafone. These are a great way to get hands-on experience in established companies that will help you to stand-out to future employers and may sometimes lead to permanent job offers with the company with which you intern.

Having a computing degree will provide you with the knowledge, problem-solving skills and logical thinking capabilities that serve as a competitive advantage across a whole range of careers. If some of the more traditional routes mentioned above don’t appeal to you, a background in computer science can also open the door to areas such as:

  • Teaching
  • IT training
  • Business analysis
  • Entrepreneurship
  • Management
  • Technical writing and journalism

How to prepare for a Computer Science degree?

The best combination of A-level subjects to study for admission to a Computer Science degree is Maths, Further Maths and Physics. Or Maths, Further Maths and Computing. We offer Maths, Further Maths and Physics in our range of A-level subjects at Kings. These are ideal for students who are 16 years old and who can take the standard two-year A-level course.

We also offer a Science and Engineering Foundation, which is based on A-levels and assured by Pearson. This is an excellent option for international students who are over 17 years old and have already completed high school in their country and need to deepen their scientific preparation in English.
