GCSE Computer Science

Computer Science is a core component of the EBacc, putting it alongside traditional sciences by recognising the high
standards of intellectual depth and practical value of this qualification. This
course enables students to learn the science behind computing and
programming skills which high-tech industries need. Many high-tech
companies originated as small start-ups founded by Computer Scientists e.g.
Microsoft, Facebook, Google and Apple.
It is important to note that Computer Science can be very challenging at times due to the nature of the
programming, maths and theoretical concepts involved. Students will be expected to attend regular support
sessions to improve their knowledge and programming skills.

What’s the difference between IT and Computer Science?

Consider a car. Most people want to learn to drive, you don’t need to know how
the car works, but you just want to get from A to B. IT is just that, it develops a
skill set so you can “drive” your computer. You don’t care how it works as long as
it helps you write a report or do the accounts. However, some people want to
know how it works. Just like car mechanics & engineers they want to get under the bonnet and understand the basic
principles. They might design better cars and invent new technologies for greener engines etc. This is the equivalent
to studying Computer Science, getting underneath the computer learning how it actually works.

Why Choose GCSE Computer Science?

The course will give students an in-depth understanding of how computer technology works and a look at what goes
on “behind the scenes”. As part of this, students will investigate computer programming in the Python language,
which students will find enjoyable, if sometimes difficult. The course will help students develop critical thinking,
analysis and problem-solving skills.

Unit 1: Computer systems
– Written Examination (50%) 1hour 30minutes
Students will learn about the hardware involved in making the computer work, the functions of operating system
software, binary and hexadecimal number systems, communications and networking, as well as the ethical, legal,
cultural and environmental impacts of digital technology. There is a small amount of mathematical content in the
exam.

Unit 2: Computational thinking, algorithms and programming

– Written Examination (50%) 1hour 30minutes

Students will learn about algorithms, how to create them and turn them into working programming projects through
the learning of programming techniques using the Python programming language. There is a large amount of
computer programming which will be in the final exam.

Practical Programming

All students will be given the opportunity to undertake a programming task, either to a specification or to solve a
problem, during their course of study. Students may draw on some of the content in both components when
engaged in Practical Programming. This is completed under classroom conditions and students will have to be
prepared to work independently on the task at hand.
