5. Assessment Overview

The assessment structure is designed to evaluate both theoretical knowledge and practical skills. There are two main routes: Core and Extended, each with specific papers. All candidates also complete a practical assessment.

Assessment Type	Paper	Duration	Marks	Weighting	Content
Core Assessment	Paper 1: Multiple Choice (Core)	45 min	40	30%	Core subject content
Core Assessment	Paper 3: Theory (Core)	1 hr 15 min	80	50%	Core subject content
Extended Assessment	Paper 2: Multiple Choice (Extended)	45 min	40	30%	Core and Supplement content
Extended Assessment	Paper 4: Theory (Extended)	1 hr 15 min	80	50%	Core and Supplement content
Practical Assessment	Paper 5: Practical Test or Paper 6: Alternative to Practical	1 hr	40	20%	Experimental skills

Key Points: Core candidates take Papers 1 and 3; Extended candidates take Papers 2 and 4. All candidates take either Paper 5 or 6 for practical assessment.

6. Support and Resources

Cambridge provides a range of support materials for teachers and students, including:

Specimen papers and mark schemes
Teacher guides and syllabuses
Online forums and discussion groups
Endorsed textbooks and resources
Results analysis and candidate reports

7. Summary Table: Main Topics Covered

Topic Number	Topic Name	Brief Description

8. Example: Stoichiometry

Definition: Stoichiometry is the calculation of reactants and products in chemical reactions using balanced chemical equations.

Key Formula:

$\text{Moles} = \frac{\text{Mass (g)}}{\text{Molar Mass (g/mol)}}$

Application: Used to determine the quantities of substances required or produced in a reaction.
Example: If 2 g of hydrogen reacts with oxygen to form water, calculate the moles of hydrogen used.

$\text{Moles of H}_2 = \frac{2\ \text{g}}{2.02\ \text{g/mol}} = 0.99\ \text{mol}$

9. Scientific Communication and Conventions

Use of standard symbols, terminology, and nomenclature is essential for clear scientific communication.
Follow IUPAC conventions for naming compounds and writing chemical equations.

10. Practical Skills and Safety

Develop competence in laboratory techniques, including measurement, observation, and data analysis.
Understand and apply safety procedures to minimize risks during experiments.

11. Assessment Objectives

Knowledge with understanding: Recall, select, and communicate chemical knowledge.
Handling information and problem solving: Apply knowledge to new situations, interpret data, and solve problems.
Experimental skills and investigations: Plan, carry out, and evaluate practical work.

12. Conclusion

The Cambridge IGCSE Chemistry 0620 syllabus provides a balanced approach to learning chemistry, combining theoretical knowledge with practical skills. It prepares students for further study and equips them with essential scientific competencies for academic and professional success.
