Official PCT Exam (Physics - Chemistry - Technology) — BEPC Session 2018

This document presents the official Physics - Chemistry - Technology (PCT) exam from the 2018 session of the Brevet d'Études du Premier Cycle (BEPC). This rich and well-balanced paper covers all three PCT disciplines and serves as a valuable reference for exam preparation. The complete answer key is included.

Exam Structure

The exam is organized according to the three standard assessment levels:

• Knowledge Assessment: this section explores a wide range of fundamental concepts. Questions cover chloride ions and calcium ions and their identification tests, petroleum refining and its by-products, the characteristics of a sinusoidal voltage (amplitude, period, frequency), the components of an electric motor (stator and rotor) and their functions, the role of the circuit breaker in an electrical installation, the phases of the 4-stroke engine cycle, and the concepts of preventive and corrective maintenance.

• Applications Assessment: the second section offers calculation and applied reasoning exercises. Students must determine the concentration of a chemical solution, calculate the forces and efficiency of a winch, analyze a gear train with transmission ratio and speed calculations, determine the compression ratio of a combustion engine, and design a parallel lamp circuit with a standardized electrical diagram. The diversity of exercises ensures a comprehensive assessment of practical skills.

• Competency Assessment: the final section addresses technical drawing with a cavalier perspective exercise. Students must represent an assembly consisting of a cylinder placed on a rectangular prism, while respecting projection conventions, proportions, and the drawing of visible and hidden edges. This exercise engages spatial vision and graphical precision.

Complete Answer Key Included

The detailed answer key provides well-argued answers, fully developed calculations, and dimensioned diagrams. It enables rigorous self-correction and helps students assimilate the resolution methods expected by BEPC examiners.

Target Audience

This paper is recommended for BEPC candidates of all sessions, PCT teachers seeking practice papers, and students wishing to deepen their skills in technical drawing, mechanics, and solution chemistry.
