Biology a natural science that studies, describes, preserves and explores life and living organisms. Despite its complexity, biology concepts are unifying for other sciences – we all acknowledge that cell is the basic unit of life, genes are the basic unit of hereditary and evolution is the driving force for origin and extension of species. But living organisms can also be studying from a physical or a chemical point of view, connecting biology to other subjects. As a fascinating post-16 discipline of study, it is regarded as an excellent preparation for students aspiring to take undergraduate degrees in the sciences, medical or biological engineering, environmental studies, and forensics among others. The Europe Tutorial Academy currently offers pre-university courses in Biology for A-level, International Baccalaureate Diploma and Advanced Placement students.
