IGCSE | Chemistry
About this course
IGCSE stands for the International General Certificate of Secondary Education. It is a special educational programme of preparation for IGCSE examinations and getting a qualification that is globally-recognised. This qualification fits into the latest educational developments and trends all over the world and can be an ideal foundation for A Level and the International Baccalaureate Diploma programs. Students normally sit five to seven subjects in the last years of their school.
Why do students need IGCSE?
IGCSE program not only gives students a chance to go to the best colleges and universities, but also helps to develop their critical and creative thinking, independence, cultural and social awareness and thus building the foundation for further academic success. Good IGCSE exam results (points 4-9) is the best way to enter the best educational institutions all over the world.
How to choose subjects for study on the IGCSE program?
Traditionally, IGCSEs are taken in 5-6 subjects, depending on which path the students choose for their future profession. The range of IGCSE subjects is really wide but the students usually choose Mathematics, Business, ICT, English, Science (Biology, Physics or Chemistry) or humanities (Literature, Geography or History). When choosing the IGCSE subjects you should also consider your own interests and preferences. As a rule, IGCSE subjects are chosen “in excess”, so that it is possible to abandon disciplines which are more difficult to cope with.
In 2013 our British Online School Knowledge Space was accredited by Edexcel to run the programs in accordance with British educational standards. Since then, our students have studied various subjects at our British School and each year most of them pass IGCSE exams.
IGCSE Chemistry. The course gives students the opportunity to experience chemistry within the context of their general education.
The aims and objectives of this qualification are to enable students to:
- acquire knowledge and understanding of chemical facts, terminology, concepts, principles and practical techniques,
- apply the principles and concepts of chemistry to different contexts,
- evaluate chemical information, making judgements on the basis of this information,
- appreciate the practical nature of chemistry, develop experimental and investigative skills,
- analyse, interpret and evaluate data and experimental methods, draw conclusions,
- recognise the importance of accurate experimental work and reporting scientific methods in chemistry,
- select, organise and present relevant information clearly and logically using appropriate vocabulary, definitions and conventions,
- develop a logical approach to problem solving in a wider context,
- prepare for more advanced courses in chemistry and for other courses that require knowledge of Chemistry.
