IGCSE Cambridge Chemistry (0620) — frequently asked questions
What is IGCSE Chemistry 0620?
Cambridge IGCSE Chemistry (0620) covers states of matter, atomic structure, bonding, stoichiometry, acids and bases, energy changes, rates, equilibrium, redox, organic chemistry and the periodic table. Paper 5 (Planning, Analysis and Evaluation) and Paper 6 (Alternative to Practical) are where many students lose marks unnecessarily.
What is Paper 6 (Alternative to Practical) in IGCSE Chemistry?
Paper 6 tests practical skills — planning experiments, identifying variables, analysing data and evaluating conclusions — without requiring the student to be in a lab. It replaces Paper 5 for schools that do not run practical exams. Both require similar preparation.
What are the hardest topics in IGCSE Chemistry 0620?
Mole calculations, electrolysis (predicting products at electrodes), organic chemistry (naming, reactions and mechanisms), and energy level diagrams are consistently the highest mark-loss areas.
