Whether you're a pharmacy student prepping for finals, a medical student studying for boards, or a healthcare professional refreshing your knowledge - Pharmingo adapts to your pace. NEW: 3D ANATOMY Learn anatomy on a real, interactive 3D model - not flat diagrams. - Rotate, zoom and pan the model with your fingers. - Tap any structure to identify it and open its knowledge card. - Peel back the layers - bones, ligaments, muscles, nerves, arteries and veins. - Training mode isolates a single structure so you can study it without distraction. - Answer questions inside the model itself: tap the named structure, or rotate to the correct anatomical view. - Live now: the Upper Limb - 43 structures spanning bones, joints, muscles, nerves and vessels, plus the clinical regions every exam asks about: the axilla, cubital fossa, carpal tunnel and anatomical snuffbox. More regions are rolling out. PHARMACOLOGY - Comprehensive curriculum covering Principles of Pharmacology, Autonomic Nervous System, Cardiovascular Drugs, CNS Medications, Antimicrobials, Endocrine Pharmacology, and more. - Question formats built for real understanding - multiple choice, fill-in-the-blank, ordering, matching, drag-and-drop, image hotspots, flashcards and dose calculations. - Intro cards and video introductions ground every lesson in real clinical context. - Mistake-only review sessions - every wrong answer is automatically queued so you study exactly where it matters. STUDY CARDS A flip-through deck sits behind every section: - Pharmacology - properly rendered formulas, dose-response curves, mnemonics, core concepts and clinical pearls. - Anatomy - concepts, bony landmarks, anatomical relations, mnemonics and clinical correlations. FULLY BILINGUAL Every lesson, question and card is written in both English and Arabic - with a per-question language toggle, so you can check a term in the other language without leaving the quiz.
