Official PCT Exam (Physics - Chemistry - Technology) — BEPC Session 2023

This document is the official Physics - Chemistry - Technology (PCT) exam from the 2023 session of the Brevet d'Études du Premier Cycle (BEPC), the national end-of-middle-school examination. It is intended for ninth-grade students preparing for this national exam, as well as for any teacher seeking an authentic and comprehensive assessment resource.

Exam Structure

The exam follows the standard BEPC format and is organized into three complementary sections:

• Essential Knowledge Assessment: this first section tests the student's fundamental knowledge through questions covering the molecule, non-biodegradable materials, the renowned Lavoisier's law (conservation of mass), the electric motor, the connecting rod-crank system, and the concept of Top Dead Center (TDC). These topics span all three PCT disciplines and verify mastery of scientific and technical vocabulary.

• Applications Assessment: the second section places the student in situations requiring the practical application of knowledge. It includes exercises on the dissolution of sodium chloride (NaCl) with concentration calculations, the use of an oscilloscope to analyze a sinusoidal voltage (reading the period, frequency, and amplitude), and the study of a single-cylinder engine with determination of its technical specifications.

• Competency Assessment: the third section presents an integrated problem where the student must draw on multiple areas of knowledge to solve a complex situation. The topic focuses on the study of a pulley-belt system designed to drive a mill, including the calculation of the belt's slip rate and the analysis of the transmission ratio.

Complete Answer Key Included

This document includes the detailed answer key for all exercises, making it a particularly effective self-assessment tool. Each answer is justified and calculations are presented step by step, allowing students to understand the expected approach and identify any mistakes they may have made.
