Description
The International A Level in Chemistry will give you essential knowledge and understanding of different areas of the subject and how they relate to each other. You will gain a deep appreciation of the skills, knowledge and understanding of scientific methods.
You will also become competent and confident in a variety of practical, mathematical and problem solving skills and develop an interest in and enthusiasm for the subject, including developing an interest in further study and careers associated with the subject.
Difference between Cambridge & Edexcel Exam Boards
Cambridge and Edexcel A Levels are international qualifications. Cambridge A-Levels can be taken worldwide including the United Kingdom, whereas Edexcel A-Levels can only be taken outside of the United Kingdom. Both Cambridge and Edexcel courses are Full A Level qualifications allowing you to apply to universities internationally.
For the sciences, (biology, chemistry and physics) there are some differences between the specifications. One main difference which will sometimes sway a decision is the assessment:
Edexcel
With Edexcel all of the specification including practical is taught in theory and as a result you will be assessed by written exam papers only.
Cambridge
If you take the sciences with Cambridge, you will have written exams but you will also need to complete practical endorsements. In order to do so, your exam centre will need to cater for both the written and practical exams.
Students will be required to arrange and pay for their examinations / practicals at an approved centre. We can provide an extensive list of these centres for you.
Progression
The course is ideal for anyone wishing to gain a knowledge and understanding of this subject or for anyone who wishes to study at a higher level at University and gain UCAS points. You will also find this course extremely valuable if you are looking for a progression route for further training whilst employed.
Other A levels which compliment this course well include Mathematics, Biology and Physics.
Cambridge Specification
International A Level Chemistry
Cambridge Course Code: 9701
Cambridge Exams: June & November
Cambridge Study Hours: 300 – 360 hours
Cambridge International Examinations (CIE)
Cambridge International AS & A Level Chemistry develops a set of transferable skills including handling data, practical problem-solving, and applying the scientific method. Learners develop relevant attitudes, such as concern for accuracy and precision, objectivity, integrity, enquiry, initiative and inventiveness. The essential scientific skills learnt will prepare learners for progression to further studies or employment.
How will I benefit from the International A Level Chemistry Cambridge course?
Cambridge International AS & A Level Chemistry encourages learners to be:
- confident, secure in their knowledge, keen to explore further and able to communicate effectively through the language of science
- responsible, developing efficient and safe scientific practices and working collaboratively with others
- reflective, able to evaluate evidence to draw informed and appropriate conclusions and recognising that the applications of science have the potential to affect the individual, the community and the environment
- innovative, applying problem-solving skills to novel situations and engaging with new tools and techniques, including information technology, to develop successful approaches
- engaged, developing an enquiring mind, keen to apply scientific skills in everyday life.
Key concepts
The key concepts for Cambridge International AS & A Level Chemistry are:
Atoms and forces
Matter is built from atoms interacting and bonding through electrostatic forces. The structure of matter affects its physical and chemical properties, and influences how substances react chemically.
Experiments and evidence
Chemists use evidence gained from observations and experiments to build models and theories of the structure and reactivity of materials. Theories are tested by further experiments and an appreciation of accuracy and reliability is gained.
Patterns in chemical behaviour and reactions
Patterns in chemical behaviour can be identified and used to predict the properties of substances. By applying these patterns, useful new substances can be designed and synthetic routes created.
Chemical bonds
The understanding of how chemical bonds are made and broken by the movement of electrons allows us to predict patterns of reactivity. Appreciation of the strength of chemical bonds leads to the understanding of a material’s properties and its uses.
Energy changes
The energy changes that take place during chemical reactions can be used to predict the extent, feasibility and rate of such reactions. An understanding is gained of why and how chemical reactions happen.
