Computer Science

Level 3

Qualification: A Level

Duration: 2 years

What will I study?

This two year course looks at how large and small computer systems are designed, developed and installed and gives practical experience of developing computer programs.

This is a linear qualification so Components 1, 2 and 3 will be delivered across the Lower and Upper Sixth.

· Component 1: A written paper which investigates programs, data structures, algorithms, logic, programming methodologies and the impact of computer science on society (40%, 2 hours 45 minutes).

· Component 2: A written paper which investigates computer architecture, communication, data representation, organisation and structure of data, programs, algorithms and software applications (40% 2 hours 45 minutes).

· Component 3: This is the practical module of the course. A substantial piece of practical work in which you will discuss, investigate, design, prototype, refine and implement, test and evaluate a computerised solution to a problem of your choice. C++ will be used as the programming language – no prior experience of this language is required. (20%).

Enrichment Opportunities

Students will benefit from access to support during daily lunchtime sessions in the Computer Science classroom. Help and support are also available via Teams and e-mail outside of college hours. Throughout the course there will be opportunities to listen to guest speakers along with potential visits to universities and employers.

Assessment

This is a two-year course leading to a full A-Level qualification. The qualification is entirely assessed at the end of Year 13. The practical work is assessed by coursework which is internally marked and externally moderated. Programming tasks will be undertaken using C++ via Visual Studio. Students will be provided with the software to install for use at home. Access to a Windows-based PC at home is highly recommended.

Entry Criteria

Grade 6 Maths. If Computer Science is taken at GCSE a minimum of a grade 5 is required. Grade 4 English Language.

Useful Supporting Courses

Students often combine Computer Science with Mathematics and Science subjects.

Students are advised against taking both Computer Science and BTEC IT (or should take careers advice before doing so).

Careers

This course could lead to a career as a Software Engineer, Systems Analyst or Network Technician. It also demonstrates good knowledge of problem solving which can be transferred to many different areas.

You could become the next Bill Gates, Steve Jobs or Mark Zuckerberg!

Data Analyst, Information Systems Manager, IT Consultant and Web Designer.
