Why study Computer Science?

Computers touch nearly every aspect of our everyday lives. The most important aspect of Computer Science is being able to solve problems. This is an incredibly useful transferable skill. This course enables students to understand the core academic principles of Computer Science, developing their technical understanding as well as their analytical and problem solving abilities.

The non-examined assessment (programming project) gives the student an opportunity to build on programming skills that they have developed at KS3 & KS4 to solve a suitable practical problem of their own choosing. Giving them real experience of project managing a programming task.

Course content/Outline:

  1. COMPUTER SYSTEMS
  • The characteristics of contemporary processors, input, output and storage devices
  • Software and software development
  • Exchanging data - compression, encryption, hashing, databases, networks & web technologies
  • Data types, data structures, Boolean Algebra and algorithms
  • Legal, moral, cultural and ethical issues.
  1. ALGORITHMS AND PROGRAMMING

SECTION A

  • Traditional questions concerning computational thinking:
  • Elements of computational thinking – logical, procedural and concurrently
  • Programming and problem solving
  • Pattern recognition, abstraction and decomposition
  • Algorithm design and efficiency
  • Standard algorithms

       SECTION B

  • A scenario/task contained in the paper, which could be an algorithm or a text page-based task, which will involve problem solving.

       03 PROGRAMMING PROJECT

External moderation

Students select their own user-driven problem of an appropriate size and complexity to solve. This will enable them to demonstrate the skills and knowledge necessary to meet the Assessment Objectives. Students will need to analyse the problem, design a solution, implement the solution and give a thorough evaluation.

Overview of theory assessment
This unit is assessed through two 2 hours 30 minute examination papers set and marked by OCR:
The total number of marks available for each examination paper is 140.
Paper 1: 40% of the A level
Paper 2: 40% of the A level

What career opportunities are there?

Computer Science is valued by higher education establishments and employers. It will allow you to study Computer Science, Engineering, Physics or related subjects. There is an opportunity for following many STEM careers, where there are many shortages of qualified people. For example, Software System Developers, Business Intelligence Analysts, Computer Programmers, Software Security, Data Analyst, Web Developer, Project Manager, Database Developer, Artificial Intelligence and Network Managers to name a few career options.
