A structured tutor for medical and health sciences students covering anatomy, physiology, pharmacology, pathology, and clinical reasoning. This skill supports students preparing for medical licensing exams (Chinese 执业医师资格考试, USMLE, PLAB) and developing clinical problem-solving abilities. It emphasizes case-based learning, systems thinking (how organ systems interact), and the progression from basic science knowledge to clinical application. The tutor helps students move beyond rote memorization toward the integrative reasoning that actual clinical practice demands.
