Cambridge IGCSE Chemistry 0620 syllabus for 2020 and 2021.1 Why choose this syllabus?Key benefitsCambridge IGCSE syllabuses are created especially for international students. For over 25 years, we have workedwith schools and teachers worldwide to develop syllabuses that are suitable for different countries, different typesof schools and for learners with a wide range of abilities.Cambridge IGCSE Chemistry enables learners to: increase their understanding of the technological world take an informed interest in scientific matters recognise the usefulness (and limitations) of scientific method, and how to apply this to other disciplines and ineveryday life develop relevant attitudes, such as a concern for accuracy and precision, objectivity, integrity, enquiry, initiativeand inventiveness develop an interest in, and care for, the environment better understand the influence and limitations placed on scientific study by society, economy, technology,ethics, the community and the environment develop an understanding of the scientific skills essential for both further study and everyday life.Our programmes balance a thorough knowledge and understanding of a subject and help to develop the skillslearners need for their next steps in education or employment.Our approach encourages learners to be:Cambridgelearner‘The strength of Cambridge IGCSE qualifications is internationally recognised and has providedan international pathway for our students to continue their studies around the world.’Gary Tan, Head of Schools and CEO, Raffles International Group of Schools, Indonesia2www.cambridgeinternational.org/igcseBack to contents page
Cambridge IGCSE Chemistry 0620 syllabus for 2020 and 2021. Why choose this syllabus?Recognition and progressionThe combination of knowledge and skills in Cambridge IGCSE Chemistry gives learners a solid foundation forfurther study. Candidates who achieve grades A* to C are well prepared to follow a wide range of courses includingCambridge International AS & A Level Chemistry.Cambridge IGCSEs are accepted and valued by leading universities and employers around the world as evidence ofacademic achievement. Many universities require a combination of Cambridge International AS & A Levels andCambridge IGCSEs or equivalent to meet their entry requirements.UK NARIC, the national agency in the UK for the recognition and comparison of international qualifications andskills, has carried out an independent benchmarking study of Cambridge IGCSE and found it to be comparable tothe standard of GCSE in the UK. This means students can be confident that their Cambridge IGCSE qualificationsare accepted as equivalent to UK GCSEs by leading universities worldwide.Learn more at idge IGCSE is one of the most sought-after and recognised qualifications in the world.
