A Level Chemistry

It is desirable that students taking Chemistry at AS or A level should have achieved at least grade B in GCSE Chemistry or BB in Double Award Science. Double Award students must be able to provide evidence of a high competence in units C1 and C2 in order to meet the demands of the AS course.

A wide range of resources to support learning beyond the AS / A2 classroom can be found at https://ids.c2kschools.net/.

From September 2015 we will be offering CCEA GCE (A-Level) Chemistry in line with the NI Education Minister’s policy that practical work must contribute to the A-Level grade of a Science.

CCEA GCE Chemistry is comprised of two levels: AS and A2. The AS can be taken as a ‘stand-alone’ qualification without progression to A2. However, to obtain the Advanced GCE qualification, students must complete both the AS and A2 levels.

The specification has a modular structure and students are required to study three modules at each level. The modules are listed below and are all compulsory:

Content of all modules.

In GCE Chemistry, students are assessed against three assessment objectives:

AO1: Knowledge and Understanding of Chemistry and How Chemistry Works

Students must be able to:

  • recognise, recall and show understanding of scientific knowledge; and
  • select, organise and communicate relevant information in a variety of forms.

AO2: Application of Knowledge and Understanding of Chemistry and of How Chemistry Works

Students must be able to:

  • analyse and evaluate scientific knowledge and processes;
  • apply scientific knowledge and processes to unfamiliar situations including those related to issues; and
  • assess the validity, reliability and credibility of scientific information.

AO3: How Chemistry Works

Students must be able to:

  • demonstrate and describe ethical, safe and skillful practical techniques and processes, selecting appropriate qualitative and quantitative methods;
  • make, record and communicate reliable and valid observations and measurements with appropriate precision and accuracy; and
  • analyse, interpret, explain and evaluate the methodology, results and impact of their own and others’ experimental and investigative activities in various ways.

From this it can be seen that Recall of knowledge (AO1) alone will not lead to success!

Students must complete six examinations: three at AS and three at A2. These are all timetabled during the Summer series and are outlined in the table below:
