About the course

The Mosslands School Chemistry Department follow the AQA examination board specification and consider this course best suited to the needs of our students

AS Chemistry

Topics studied include:

  • The structure of atoms and how atoms join together into larger structures.
  • Energy changes in chemical reactions and the practical results of reversible reactions including equilibria.
  • A study of the elements in groups 2 and 7 of the Periodic Table and how the chemical and physical properties of these elements change within their Groups.
  • The structures and chemical reactions of simple organic (carbon) compounds including hydrocarbons and alcohols.
  • Quantitative chemistry. Including calculating the masses or volumes of substances produced in chemical reactions.
  • There is also a section assessing practical skills in chemistry.
  • These topics all build on topics covered during the Year 11 Chemistry course.

A2 Chemistry

  • The topics covered are more demanding than those in the AS course and include:
  • Reaction kinetics, which involves the equations governing the speeds of chemical reactions.
  • Factors affecting equilibria and how these are taken into account in the chemical industry.
  • Acids and bases.
  • The structures and reactions of some more complicated organic (carbon) compounds including aldehydes, ketones, carboxylic acids and benzene and other aromatic compounds.
  • Electrical chemistry.
  • The chemistry of the transition metals, including their reactions, colours and uses.
  • Again, there is a section assessing practical skills in Chemistry.

How it will be assessed?

In Chemistry, the examination structure comprises 2 externally assessed, written examinations and 1 internally assessed and externally moderated exercise at each of AS and A2, making 6 units of assessment altogether.

Qualification Details

AS and A2 Chemistry

Entry Requirements

At least 5 A*-C grades at GCSE.

Students who wish to take Chemistry at A-level need to achieve A* - B grade at GCSE Chemistry.

What is expected of you?

You will be expected to attend all lessons and complete all tasks on time. There is a section on chemical calculations which will require a basic competency in Maths. You will need to cope with the pressure of homework set most lessons and two sets of module exams per year.

What it prepares you for?

Higher Education

The study of A-level Chemistry supports the study of all of the Science subjects, including Chemistry and Chemical engineering, at University and also supports many related subjects. In recent years, former Mosslands A-level students have gone on to University to study Medicine, Pharmacy, Dentistry and Psychology as well as Chemistry and the other Sciences.


The study of Chemistry at A-level supports any career which requires numeracy, logic or scientific skills. These can be as diverse as Chemical Engineering, Oceanography,

Medicine and Accountancy.
