Computer Science AS level at Chace Community School

Course description

The content of this AS Level in Computer Science is divided into two components. 

•       Computing principles component (01) contains the majority of the content of the specification and is assessed in a written paper recalling knowledge and understanding.

•       Algorithms and problem solving component (02) relates principally to problem solving skills needed by learners to apply the knowledge and understanding gained through the Computing principles component.

Computer Science uses mathematics to express its computational laws and processes.  Mathematical skills are embedded throughout the content of the two components and assessed in the written papers where appropriate. 

Learners must take both components (01 and 02).   

Computing principles (01) 

•       The characteristics of contemporary processors, input, output and storage devices

•       Software and software development

•       Programming

•       Exchanging data

•       Data types, data structures and algorithms

•       Legal, moral, ethical and cultural issues 

Algorithms and problem solving (02) 

•       Elements of computational thinking

•       Problem solving and programming

•       Algorithms 

Component (01) will introduce learners to the internal workings of the Central Processing Unit (CPU), the exchange of data and will also look at software development, data types and legal and ethical issues. It is expected that learners will draw on this underpinning content when studying computational thinking and developing programming techniques. 

Learners will be expected to apply the criteria in different contexts including current and future uses of the technologies.

Component (02) will incorporate and build on the knowledge and understanding gained in the Computing principles component. In addition, learners should:

•       understand what is meant by computational thinking

•       understand the benefits of applying computational thinking to solving problems

•       be able to use algorithms to describe problems. 

Entry requirements

You will need a B grade or above at GCSE in Mathematics. In addition, a GCSE in Computing is desirable, but not essential. 


This AS Level in Computer Science qualification is a linear qualification with 100% terminal external assessment. 

This qualification consists of two examined components (01 and 02), both examinations are of 1 hour and 15 minutes duration, each with a 50% weighting. 

Future opportunities

Computer Science is relevant in this modern and changing world. This specification will:

•       Focus on programming, building on OCR’s GCSE Computing and emphasise the importance of computational thinking as a discipline. 

•       Have an expanded maths focus, much of which will be embedded within the course.

•       Put computational thinking at its core, helping students to develop the skills to solve problems, design systems and understand human and machine intelligence.

•       Allow student to apply the academic principles learned in the classroom to real world systems in an exciting and engaging manner.

•       Give students a clear progression into higher education, as the course was designed after consultation with members of BCS (British Computer Society), CAS (Computing at School) and top universities.
