Cambridge International AS Level Computer Science (9618) Syllabus

Fee:

BWP 2,000

Duration:

2 Years

Overview

This AS stage provides a strong balance between theory (hardware, networks, systems) and practical coding/database work. Cambridge provides a pseudocode standard for teaching/programming that all exams use.

Modules

Paper 1: Theory Fundamentals

1. Information Representation

  • Binary systems & conversions
  • Hexadecimal
  • Number representation (signed, unsigned, floating-point)
  • Text, images, sound representation
  • Compression methods

2. Communication & Internet Technologies

  • Data transmission (serial/parallel, synchronous/asynchronous)
  • Error detection/correction
  • Network topologies & protocols
  • Client–server model, internet structure
  • IP addressing, DNS

3. Hardware

  • Structure & architecture of processors (ALU, control unit, registers, buses)
  • Input, output & storage devices
  • Logic gates & circuits

4. Processor Fundamentals

  • Fetch–decode–execute cycle
  • Machine code instructions
  • Assembly language basics

5. System Software

  • Operating system functions
  • Utility software
  • Language translators (compiler, interpreter, assembler)

6. Security, Privacy & Data Integrity

  • Threats to computer systems
  • Authentication, encryption, firewalls
  • Backup strategies, validation, verification

7. Ethics & Ownership

  • Intellectual property
  • Environmental issues
  • Impact of computer use in society

Paper 2: Fundamental Problem-solving & Programming Skills

1. Algorithm Design & Problem-solving

  • Pseudocode & flowcharts
  • Algorithm efficiency
  • Searching & sorting algorithms (linear/binary search, bubble/insertion/merge sort)

2. Programming

Basic constructs: sequence, selection, iteration
Data types & structures (arrays, records, files)
Procedures & functions
Structured programming principles

3. Databases

  • Database concepts
  • Relational databases
  • SQL basics (queries, selection, joins)

Assessment at AS Level


  • Paper 1 (Theory Fundamentals) – 1h 45min written exam – 50% of AS
  • Paper 2 (Practical/Programming) – 1h 45min on-screen exam – 50% of AS


Together, these two form the AS qualification.

For full A Level, learners add Paper 3 (Advanced Theory) and Paper 4 (Advanced Practical) in Year 2.
