Science Double Award (Chemistry) IGCSE

The course

GCSE Chemistry is divided into four sections. In Section 1 (Principles of chemistry), you will look at the structure of atoms and compounds, chemical formulae and equations and how to calculate the masses of substances and volumes of gases. In Section 2 (Chemistry: the elements), you will look at the periodic table, with a particular focus on groups 1 and 7.

You will also look at hydrogen, oxygen and oxides, and water. Section 3 (Organic chemistry) looks at the chemistry of carbon. You will look at two different types of organic compound (alkanes and alkenes) and ethanol. Finally in section 4 (Physical chemistry) looks at acids, alkalis and salts and chemical reactions: reaction rates and the ideas of equilibrium and reversibility.

What skills do I need?

You need an interest in science along with good mathematical skills.

How is the course assessed?

All the content will be assessed through a 2-hour written examination. The paper is weighted at 33.3% of the qualification. A mixture of different question styles, including multiple-choice questions, short answer questions, calculations and extended open response questions.
