Students say

“Really fascinating to know how computers actually work.”

“The course is technical but if you think logically you can work it all out.”

WHY STUDY THIS SUBJECT?

The course gives students an in-depth understanding of how computer technology works. Although students will have used the technology before, this course gives them an insight into what goes on ‘behind the scenes’, including computer programming, which many students find absorbing.

Nationally there is a growing demand for professionals who are qualified in this area. Students who take this subject at A Level will open up a number of fascinating and very well paid careers.

WHAT SKILLS WILL I DEVELOP?

The focus will be on programming with an emphasis on the importance of computational thinking as a discipline. Students will also apply maths to understand computing logic. They will develop the skills to solve problems, design systems and understand human and machine intelligence. They will also apply academic principles to real world systems.

The course will develop critical thinking, analysis and problem-solving skills through the study of computer programming. These skills can then be transferred to other subjects.

WHAT WILL I STUDY?

COMPUTER SYSTEMS

Component 01 – Computer systems – this component will introduce you to the internal workings of the Central Processing Unit (CPU), the exchanging of data, and also looks at software development, data types and legal and ethical issues.

The characteristics of contemporary processors, input, output and storage devices
Software and software development
Exchanging data (How data is exchanged between different systems)
Data types, data structures and algorithms
Legal, moral, cultural and ethical issues.

Component 02 – Content of Algorithms and programming – you will understand what is meant by computational thinking, and understand the benefits of applying computational thinking to solving a wide variety of problems.

Elements of computational thinking
Problem solving and programming
Algorithms

Component 03 – Programming project – you will analyse, design, develop, test, evaluate and document a program written in a suitable programming language for real users.

ALGORITHMS AND PROBLEM SOLVING

How to design, build and test computer programs.

HOW WILL I BE ASSESSED?

20% Coursework versus 80% exams.

This is a two-year, linear course; the exams will take place at the end of the course.

Examination – two exams, each of 2 hours 30 mins (80%) – components 1 and 2.

Coursework – system development project (20%) – component 3.

WHAT ARE MY POST-18 OPTIONS?

There is clear progression from A Level Computer Science into higher education Computer Science or IT courses.

This course is highly suitable for a range of technical IT careers such as software development, networking design & analysis and datacentre management. We have had students take up roles like these with top IT companies such as IBM.
