Build solid biology skills for exams and beyond with a free online course, videos and practice questions on cells, enzymes, genetics, ecology and more.
In this free course, learn about
Key characteristics for classifying organisms, including arthropods/invertebrates
Cell organisation: organelles and functions, incl. ribosomes in protein synthesis
Movement across membranes: diffusion, osmosis, active transport; water potential ideas
Biological molecules: proteins, carbs, lipids; elements like nitrogen unique to proteins
Enzyme action: specificity, lock-and-key/active site, effects of temperature and pH
Plant nutrition: photosynthesis equation, limiting factors, gas exchange in light
Transport in plants: root hair adaptations, xylem/phloem roles, transpiration factors
Human nutrition: balanced diet, vitamin D deficiency and rickets; bile in digestion
Transport in animals: heart/vessels, aorta function, artery vs vein vs capillary features
Gas exchange in humans: alveoli, ventilation and blood flow maintaining gradients
Respiration vs breathing: aerobic respiration basics and energy release concepts
Excretion and homeostasis: lungs removing CO2; nervous/endocrine coordination basics
Immunity and disease: white blood cell roles; antibiotic resistance causes and impacts
Strengthen your biology foundation with a free online course designed for students who want clear understanding and steady progress, whether you are preparing for school assessments or working toward Cambridge IGCSE Biology (0610) exams. Instead of memorizing disconnected facts, you will develop the ability to explain biological ideas and apply them to unfamiliar questions, the skill that makes the biggest difference in exam performance.
The lessons guide you from core characteristics of living organisms and biological organization into the essential processes that keep cells and whole organisms functioning. You will build confidence with movement of substances across membranes, key biological molecules, and how enzymes work in living systems. From there, you will connect plant structure to function through photosynthesis, gas exchange, transport, and factors that affect transpiration, so you can reason about real scenarios rather than rely on guesswork.
Human biology is treated with the same practical focus. You will reinforce concepts in nutrition and digestion, then link transport in animals to heart and blood vessel function, gas exchange, respiration, and excretion. You will also explore coordination and response, including the nervous system and hormones, and develop a clearer picture of how the body maintains internal stability.
To support application and recall, the course pairs video explanations with targeted exercises that mirror the style of common exam questions. These practice checks help you spot gaps early, correct misconceptions, and improve your accuracy under time pressure.
Beyond the individual organism, you will broaden your understanding with inheritance, variation, natural selection, and ecology, including human impacts on ecosystems and processes such as nutrient cycling. The course finishes by introducing biotechnology ideas that link biology to modern scientific and medical advances. Learn at your own pace, revisit difficult topics anytime, and turn your study time into measurable improvement.
