This page and the links on this page are to help you make the best choice in IGCSE Science.

Use this page to find more information about the IGCSE courses themselves. You will find the main sections of each course as well as the subject specification which gives more detail about what you will learn and how you will be assessed. The assessment is the same for all three IGCSE sciences.
At the bottom of the page you will find links to other wikispaces which will have mainly information on careers in the three sciences.

IGCSE Biology

Main sections in the course are:
  1. The nature and variety of living organisms: characteristics of living organisms, variety of living organisms.
  2. Structures and functions in living organisms: levels of organisation, cells structure, biological molecules, movement of substances in and out of cells,
  3. Nutrition, respiration, gas exchange, transport, excretion, coordination and response.
  4. Reproduction and inheritance: reproduction, inheritance.
  5. Ecology and the environment: organisms in the environment, feeding relationships, cycles within ecosystems, human influences on the environment.
  6. Use of biological resources: food production, selective breeding, genetic modification, cloning.
