Tips to Study IGCSE Chemistry Syllabus

  • To excel in IGCSE Chemistry, it is important to focus on the assessment objectives—knowledge, problem-solving, and experimental skills. Since AO1 (knowledge) contributes 50% of the total marks, a solid understanding of core concepts is crucial. However, AO2 and AO3 should not be overlooked, as problem-solving and practical skills make up the remaining 50% of the final grade.
  • The syllabus covers both Core and Extended topics, but mastering the fundamentals in Core topics like atomic structure, bonding, and reactions is key. Once these are understood, tackling the more advanced Extended material becomes much easier.
  • Practical knowledge plays a significant role, especially for Paper 5 (Practical Test) and Paper 6 (Alternative to Practical). It’s not enough to just read about experiments; students should actively practice drawing experimental setups, interpreting results, and understanding lab techniques. Whether opting for the Practical Test or the Alternative, hands-on learning will greatly improve your grasp of essential skills.
  • IGCSE Past papers should be used strategically to familiarize yourself with exam formats and question types. Rather than just answering the questions, carefully analyze the mark schemes to see how examiners grade responses. Simulating exam conditions while practicing can help with time management, and identifying weak areas will build your confidence for the real exam.
  • Finally, ensure you are studying with the latest syllabus version. IGCSE updates its syllabus periodically, so it’s vital to stay updated with the current changes, especially regarding assessment objectives and topics. This helps to avoid surprises and ensures you’re fully prepared for what the exams require.
