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. Therefore, students will need to have a PPG of a
grade 4a,4b or 4c in Maths in the Year 9 spring reports in order to access the course.

What Is the difference between IT and Computer Science?

Consider a car. Most people want to learn to drive; you do not 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 do not
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 and 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 tasks given.
