Welcome, students! This specialized section contains syllabus breakdowns, core study notes, targeted practice question banks, and actual exam past papers organized dynamically to optimize your learning and help you achieve an A* (Grade 9).

1. Course Introduction

CIE IGCSE Chemistry (Syllabus Code: 0620) provides students with a detailed and comprehensive understanding of the technological world in which they live, and an informed interest in science and scientific developments. Students learn about the basic principles of chemistry through a mix of theoretical study and practical investigations, developing essential skills for further academic pathways (such as A-Level or IB DP Chemistry).

Assessment Outline

The CIE IGCSE Chemistry 0620 course is assessed through three papers. Candidates who have studied the Core syllabus content are entered for Paper 1, Paper 3 and either Paper 5 or Paper 6. Candidates who have studied the Extended syllabus content (Core and Supplement) are entered for Paper 2, Paper 4 and either Paper 5 or Paper 6.
