A guide for Students

Revision checklist for IGCSE Chemistry 0620 A guide for students How to use this guide The guide describes what you need to know about your IGSCE Chemistry examination. It will help you to plan your revision programme for the theory examinations and will explain what the examiners are looking for in the answers you write. It can also be used to help you to revise by using tick boxes in Section 3, ‘What you need to know’, to check what you know and which topic areas you have covered. The guide contains the following sections: Section 1: How will you be tested? This section will give you information about the different types of theory and practical examination Papers that are available. Section 2: What will be tested? This section describes the areas of knowledge, understanding and skills that you will be tested on. Section 3: What you need to know This shows the syllabus content in a simple way so that you can check: • the topics you need to know about • how the Extended syllabus (Supplement) differs from the Core syllabus • details about each topic in the syllabus • how much of the syllabus you have covered Appendices This section covers the other things you need to know such as: • how you can make the most of the copy of the Periodic Table that you are given in the exam • how to use the table of tests for particular chemical groups • the importance of the command words the Examiners use in the examination Papers • information about the mathematical skills you need Not all the information will be relevant to you. For example, you will need to select what you need to know in Sections 1 and 3, by finding out from your teacher which examination Papers you are taking. Section 1: How will you be tested? 1.1 The examination Papers you will take You will be entered for three examination Papers, two theory Papers and one practical Paper.

You will need to ask your teacher which practical Paper you are taking. Nearer the time of the examination, you will also need to ask which theory Papers you are being entered for. If your teacher thinks that you should enter for the examination based on the Core syllabus, you will take Paper 1 (theory), Paper 2 (theory) and one of the practical Papers (4 or 5 or 6). If your teacher thinks that you should enter for the examination based on the Extended syllabus, you will take Paper 1 (theory), Paper 3 (theory) and one of the practical Papers (4 or 5 or 6). Whether you take Paper 2 or 3 will depend on the progress your teacher thinks you have made and which Paper most suits your particular strengths. You should discuss this with your teacher. 1.2 About the theory Papers The table gives you information about the theory Papers Paper number Paper 1 How long and how many marks? 45 minutes (40 marks) 1 ¼ hours (80 marks) What’s in the Paper? 40 multiple-choice questions.

1.3 About the practical Papers Twenty percent of the marks for IGCSE Chemistry are for practical work. Practical work is based only on the Core syllabus. You will do one of the practical Papers shown in the table. Your teacher will tell you which practical Paper you will do. The number of marks varies between the Papers, but your final mark will be calculated so that it is worth the same percentage of the total examination as the other practical Papers.
