This sheet provides the official Life and Earth Sciences (SVT) and Education in Environment, Hygiene and Biotechnology (EEHB) examination from the BEPC 2021 session in Cameroon. The document includes the complete exam paper along with its full answer key, offering candidates a comprehensive and rigorous preparation tool.

The examination is structured around two main parts. Part A, devoted to resource evaluation, begins with Multiple Choice Questions (MCQs) covering essential syllabus topics: sedimentary rocks and their origin (organic, detrital), cellular chromosomes and their location, the chronological order of sedimentary rock formation (erosion, transport, sedimentation, diagenesis), and the functioning of the cardiac cycle with the concept of diastole. The Open Response Questions (ORQs) require defining the terms ecosystem and sedimentary rocks, and justifying why deforestation poses a threat to biodiversity.

The practical skills and attitudes section features an exercise on identifying immune cells from microscopic observation of a blood smear. Students must recognize different types of leukocytes, identify those involved in phagocytosis, those that secrete antibodies, and those that destroy through direct contact. A second exercise addresses environmental protection and sustainable management of natural resources.

Part B assesses competencies through a contextualized life situation focused on the fight against malaria. Despite government efforts (distribution of insecticide-treated bed nets, free treatment for pregnant women), malaria continues to take its toll. Students must analyze this situation and propose complementary control strategies.

This examination covers a broad spectrum of skills: geology (sedimentary rocks, diagenesis), immunology (immune cells, phagocytosis), cardiovascular physiology (cardiac cycle), and ecology (biodiversity, deforestation). The detailed answer key accompanying the paper enables effective self-correction and helps students understand examiners' expectations. This sheet constitutes an essential revision resource for any BEPC candidate wishing to consolidate their knowledge in SVT/EEHB and approach the examination with confidence.
