Medical Sciences
Mock Exam
Course Introduction
Medical Sciences is an interdisciplinary field that explores the structure, function, and diseases of the human body at molecular, cellular, and systemic levels. This course provides foundational knowledge of key disciplines such as anatomy, physiology, biochemistry, pathology, pharmacology, and microbiology. Students will examine the underlying mechanisms of health and disease, learn about diagnostic and therapeutic strategies, and discuss current research and innovations in medicine. The course aims to develop critical thinking, problem-solving, and analytical skills essential for healthcare and biomedical careers, while laying the groundwork for advanced study in medical and allied health professions.
