AS & A2 Level Chemistry Print Page

Aims of the Course

The specification aims to stimulate students’ interest in and enjoyment of Chemistry. The course shows the inter-relationship between the development of the subject and its applications: social, economic, environmental and technological. Students will developskills in laboratory procedures and techniques and carry these out with due regard for safety. Students will understand the link between theory and experiment. Chemistry at both AS and A2 levels aims to foster imaginative and critical thinking as well as the acquisition of knowledge, together with an appreciation of the intellectual discipline that the subject entails. In studying Chemistry, students will develop and use varying practical techniques, observe trends in the behaviour of substances. They will also solve chemical problems using mathematical techniques and concepts. Successful study of Chemistry leads to further or higher education or to direct employment in many scientific and related fields.

The specification offered in Chemistry at St. Peter’s High School is EDEXCEL: Advanced Subsidiary (AS) 8080 and Advanced GCE (A2) 9080.

Scheme of Assessment

AS Chemistry involves 3 units with a further 3 units at A2 level.The units are designed so that Units 1, 2 and 3 are taught in the first (AS) year of the course. It is important to remember that the standard of questions at any stage in the course is that expected at the end of the course.By its nature, Chemistry is a highly practical course and 40% of the time available is dedicated to experimental work. The assessment objectives for the practical coursework are:

  • A: Planning and design
  • B: Manipulation
  • C: Observing and recording
  • D: Interpretation and evaluation of experimental results

The practical coursework is internally assessed and moderated by the examinations board.
