Type of Assessment

Weighting

Unit 1 – This unit investigates hardware, logical operations, communication, data representation and data types, operating
systems, principles of programming, software engineering,
program construction, security and data management and the
impacts of digital technology on wider society.
Written examination: 1hr 45mins.
100 marks.

Unit 2 – This unit investigates problem solving, algorithms and programming constructs, programming languages, data structures and data types and security and authentication On-screen examination: 2hrs.
60 marks.
30%
Unit 3 – This unit requires learners to produce a programmed solution to a problem. They must analyse the problem, design a solution to the problem, develop a final programmed solution, test the solution and give suggestions for further development of the solution. Throughout the production of the solution learners are required to produce a refinement log that evidences the development of the solution
Non -exam assessment: 20 hour.
