Computer Science Mock Exam - BEPC 2021 - Lycee Bilingue de Baleng

This mock Computer Science exam, designed for the preparation of the BEPC 2021 session, is a comprehensive paper covering the three main sections of the official Computer Science curriculum in Cameroon. It comes with a detailed answer key, making it a particularly effective revision tool for Form Four students.

Part 1: Microcomputer Architecture and Information Representation (8 marks)

• Exercise 1 - Microcomputer Architecture: Through a practical scenario (purchasing peripherals), the student is required to define the concept of a peripheral, distinguish between input, output, and mixed peripherals, identify storage and printing equipment, and suggest antivirus software. This exercise assesses the student's ability to recognize and classify computer hardware.
• Exercise 2 - Information Representation: Questions focus on numeration systems (binary, decimal, octal, hexadecimal), their respective symbols, and the difference between structured and unstructured data. The student must master the fundamentals of digital information representation.

Part 2: Digital Citizenship (5 marks)

• Based on a text about fake news spread during the 2016 American presidential campaign regarding Hillary Clinton, the student must define the concepts of information and fake news, provide synonyms, state the criteria for reliable information, analyze the motivations behind disinformation, assess the consequences of fake news, and propose countermeasures. A question also covers Cameroonian national legislation on cybercrime.

Part 3: Introduction to Algorithms and Software Development (7 marks)

• Exercise 1 - Algorithms: The student must analyze a complete algorithm featuring display instructions, reading instructions, and a complete alternative structure (If...Then...Else). They must identify the various elements and simulate execution with a given value.
• Exercise 2 - Software Development: Questions cover the definitions of programming and programming languages, as well as the stages of the software development lifecycle, particularly coding and design.

This exam is an excellent training resource for any BEPC candidate, allowing them to assess their knowledge of hardware architecture, information representation, digital citizenship, and algorithms. The included answer key enables thorough self-assessment.
