AS/A2 Chemistry

AS/A2 Chemistry Course details
In the AS course there are two exams of 1 hour 30 minutes, each covering work from the four modules. Each paper carries 50% of the marks.

AS Level Chemistry
Module 1:
This develops your practical skills.
There is no grading of practical in Year 12 but the experiments done will count towards the A2 practical assessment.

Module 2:
Foundations in Chemistry.
In this module you will study atomic structure in detail and learn how chemists calculate amount of substance. You will become confident with equations, and will study redox and acid-base reactions.

Module 3:
Periodic Table and Energy.
This module covers periodicity and the chemistry of groups 1 and 7. You will study equilibrium, energy changes in reactions and reaction rates. Qualitative analysis is also covered.

Module 4:
In this module you will study the chemistry of carbon compounds, covering basic concepts. This is followed by the specific chemistry of hydrocarbons, alcohols and haloalkanes. Synthesis and analysis (infra red spectroscopy and mass spectrometry) are also studied.

A Level Chemistry

In the A Level course there are two exams of 2 hours 15 minutes, each carrying 37% of the marks. The other 26% is from a synoptic paper.
There is also a practical endorsement, reported separately.
There are two additional teaching modules.

Module 5:
Physical Chemistry and Transition Elements.
This involves a quantitative treatment of reaction rates and equilibrium. Buffers and pH are covered and you will study the relationships between enthalpy, entropy and free energy. Redox potential and electrode potential will be studied, along with the chemistry of transition elements.
Module 6:
Organic Chemistry and Analysis.
This module builds on the material from module 4 to cover aromatic compounds, carbonyls, carboxylic acids and esters, nitrogen-containing compounds and polymers.

Further synthesis is studied, and chromatography and nuclear magnetic resonance  are covered.
Assessment:
Paper 1 & 2 assess content from modules 1, 2, 3, 5 and 1, 2, 4, 6 respectively.
Paper 3 assesses content from all modules 1 – 6.

What could I go on to do after the course?

Science or any related science or engineering course. Chemistry is essential for studying medicine, pharmacy,  veterinary science and dentistry.

It is highly regarded as a support subject for non-science subjects, particularly for entry to numerate or technical professions e.g. accounting and patent law.
